Changelog

Delete AiSuggestionPanel view, AiSuggestionPanelViewModel, and

AiSuggestionCardViewModel — all dead code superseded by the global

AI chat tray. Remove the obsolete AiSuggestionPanel property and

its instantiation from NotesViewModel.AI.cs.

Set UserPromptLabel on all ContentSuggestionCard pushes so the chat-style

AI tray can render proper user bubbles ("Summarize this block", "Rewrite

this block", etc.) instead of synthesizing from the title.

Bump Notes plugin version to 1.54.0.

The filter TextBox was bound to RootPages.Count for visibility, so when filtering

produced zero results the filter box vanished — making it impossible to clear the

filter. Added HasAnyPages property backed by the unfiltered _allRootPages list so

the filter box stays visible whenever pages exist, regardless of filter results.

Also updated the "No pages yet" empty state to use HasAnyPages so it only shows

when there are truly no pages, not when a filter just has no matches.

The ToolbarHoverZone panel was always 120px tall at ZIndex 1,

blocking pointer events over the Add Cover button area below.

The 120px height is only needed when a cover image exists (to

create a hover zone for toolbar fade-in). Without a cover image,

the panel now auto-sizes to the toolbar's natural height, so

pointer events reach the Add Cover button underneath.

Fixed bold selector for selected TreeViewItem by using direct child

combinator path through the DataTemplate content hierarchy. Reduced

TreeView horizontal margin from 10 to 4 and set TreeViewItem padding

to 0 to reclaim horizontal space for page titles and icons.
