🔴 Sidebar menu entries open the wrong screens after a blank spacer row was added
A blank spacer row was inserted into the sidebar list (<ListBoxItem Content=""/> at ModbusForge.Avalonia/Views/MainView.axaml:74) without updating the list-to-screen mapping, so every entry below it opens the wrong screen.
Impact: Clicking Registers, Coils, Console, Debug etc. takes the user to a different section than the one they clicked, and the last entry can select nothing.
Index mapping in NavigationIndexConverter is position-based
ModbusForge.Avalonia/Converters/NavigationIndexConverter.cs:15-32 maps navigation list positions 0..14 to tab indices, assuming exactly 15 items in the original order (Dashboard..Debug). The new empty item occupies position 7, which the converter maps to tab 7 (Holding Registers), and shifts "Registers".."Debug" to positions 8..15. Position 15 is out of range for NavigationToTab so ConvertBack returns 0 (Dashboard). Also, Convert (tab -> list index) still returns pre-shift indices, so the highlighted row no longer matches the displayed tab. The blank item is also focusable/selectable, which it should not be if intended as a separator.
Prompt for agents
A blank ListBoxItem was added as a visual separator in the navigation ListBox in ModbusForge.Avalonia/Views/MainView.axaml (around line 74). The ListBox's SelectedIndex is bound through NavigationIndexConverter (ModbusForge.Avalonia/Converters/NavigationIndexConverter.cs), which maps list positions to tab indices positionally and assumes exactly the 15 original entries. Inserting an extra item shifts all subsequent entries by one, so selections map to the wrong tab and the highlight no longer follows the active tab. Either remove the blank item and achieve spacing via the existing Margin on the 'Registers' item, or use a non-selectable separator plus update the converter's mapping table (and its reverse mapping) to account for the extra row.

🔴 Application fails to start because theme resources are placed in the styles list with an undeclared namespace
A resource dictionary of colors, fonts and sizes was placed inside the application's styles collection (<ResourceDictionary> at ModbusForge.Avalonia/App.axaml:10) using an XML prefix that is never declared, so the application markup cannot be loaded.
Impact: The app cannot start / build, and none of the new theme colors are actually usable anywhere.
Three separate defects in the same block
Application.Stylesis anIStylecollection; aResourceDictionaryis not a style and cannot be added there. Application-level resources belong in<Application.Resources>.- The
sys:prefix used atModbusForge.Avalonia/App.axaml:40-44and55-56is never declared (noxmlns:sys="clr-namespace:System;assembly=netstandard"on the root element atModbusForge.Avalonia/App.axaml:1-4). <sys:Double x:Key="ControlPadding">12,8</sys:Double>(line 56) is not a validdouble; it should be aThickness.
Prompt for agents
In ModbusForge.Avalonia/App.axaml the new theme resources are declared as a ResourceDictionary nested inside Application.Styles, which only accepts IStyle instances. They should live in an Application.Resources block instead. Additionally the sys: prefix used for the sys:Double entries is not declared on the root Application element, and the ControlPadding entry uses a Thickness-style value ('12,8') typed as a double. Move the dictionary into Application.Resources, declare xmlns:sys="clr-namespace:System;assembly=netstandard", and change ControlPadding to a Thickness.

🔴 New navigation style block is malformed and never applied
A styling block was added to the view's resources with an invalid attribute (<Style Setter="Background" .../> at ModbusForge.Avalonia/Views/MainView.axaml:26) and is not referenced by any control, so it cannot be parsed and has no effect.
Impact: The markup fails to load, and even if loaded the intended navigation styling would never be applied.
Details
Style has no Setter property, so <Style Setter="Background" Value="#2D2D30"/> at line 26 is invalid markup. Furthermore, in Avalonia a keyed Style in UserControl.Resources must be applied via Theme/StyleInclude-style references; the key NavigationItemStyle is not referenced anywhere in the file — the actual navigation ListBox uses its own inline ListBox.Styles block at ModbusForge.Avalonia/Views/MainView.axaml:49-66, making this whole block dead markup.
Prompt for agents
The NavigationItemStyle block added to UserControl.Resources in ModbusForge.Avalonia/Views/MainView.axaml (lines ~13-33) contains an invalid element '<Style Setter="Background" Value="#2D2D30"/>' (Style has no Setter property) and is never referenced anywhere — the navigation ListBox defines its own inline styles. Remove the dead block, or fix the invalid element and actually reference the keyed style.

🟡 Extra documentation markdown file added against repository policy
A new top-level markdown document was added (UI_IMPROVEMENTS.md), while the repository guidelines require changes to be documented in the existing README changelog rather than in new markdown files.
Impact: The repository accumulates ad-hoc documentation files the maintainer explicitly asked not to have.
Rule reference
AGENTS.md -> "Release Files Policy": "Do NOT create extra markdown files for releases. ... ✅ Update: README.md changelog section".
Prompt for agents
AGENTS.md forbids creating extra markdown files; the UI changes should be summarized in the README.md changelog section instead. Remove UI_IMPROVEMENTS.md and fold the relevant notes into README.md.

🟨 Production configuration file no longer ignored by git
The ignore rule for appsettings.Production.json was removed from .gitignore (line 37 area, previously under "# Configuration files"), so production configuration — which typically holds connection strings, endpoints and credentials — can now be accidentally committed to the repository.
