Changelog

Replace the individual gist source picker with a "Sync All Gists" button that

pulls every user gist as a collection in a single operation. Replace the inline

"Publish as Gist" dialog in both Snippets and Notes with a gist picker modal

that lets users add files to existing gists or create new ones.

Snippets plugin:

• GistSyncService: add SyncAllGistsAsync() for bulk gist discovery/sync,

add AddSnippetToExistingGistAsync() for adding files to existing gists

• GistSourcesViewModel: remove add-source flow (IsAddingSource, gist picker

list, LoadAvailableGistsAsync), add SyncAllGists command with progress

• GistSourcesOverlay: remove gist picker panel, update empty state text,

replace footer with "Sync All Gists" button + progress indicator

• New GistPickerViewModel + GistPickerOverlay: two-tab picker (add to

existing gist from local GistSources, or create new gist)

• SnippetsViewModel: replace ShowPublishGistDialog/CancelPublishGist/

ConfirmPublishGist with PublishToGistAsync using the new picker

• SnippetsView: remove inline publish panel, add GistPickerOverlay

Notes plugin:

• GistPublishService: add ListUserGistsAsync() with pagination and

AddToExistingGistAsync() with duplicate filename handling

• New GistPickerViewModel + GistPickerOverlay: two-tab picker (add to

existing gist from GitHub API, or create new gist)

• NotesViewModel: replace fire-and-forget PublishToGistAsync with picker

workflow that returns gist URL on confirm

• NotesView: add GistPickerOverlay

Snippets 1.9.0 → 1.10.0, Notes 1.65.2 → 1.66.0

Use proper ColumnDefinition with pixel width (340, min 280, max 600)

instead of Auto column with Border.Width — GridSplitter cannot resize

Auto columns. Add hover styling and resize cursor to the splitter for

a visible drag handle.

The flyout was being populated via a Button.Click handler, but the

MenuFlyout renders before Click fires. Switch to the flyout's

Opening event so items are populated before the flyout is displayed.

• Article list panel now resizable via GridSplitter (min 280, default

340, max 600) instead of fixed ThemeDetailPanelWidth

• List items use Grid for star+title layout so TextTrimming works

correctly (ellipsis instead of overflow), increased item margin

• Feed selector dropdown now shows all default categories (Tech,

News, Business, Science, Design) as bold headers, with feeds

indented under their category, and Uncategorized feeds at bottom

• Each feed in the dropdown has a right-click context menu for

Rename Feed, Set Category, and Remove Feed

• Category headers are clickable to filter by that category

Remove the sidebar entirely — feeds are now selected via a dropdown

button in the toolbar. The dropdown shows "All Feeds" at the top,

then each category as a bold header (clicking selects all feeds in

that category), with individual feeds indented underneath.

• Add SelectedCategory property for category-based filtering
• Add SelectCategoryCommand and FeedSelectorLabel computed property
• Category filtering is client-side (filters loaded articles by

feed IDs belonging to the selected category)

• Feed selector button shows current selection label with caret
• Focus mode star also updated from emoji to PathIcon glyph
