Changelog

Increased TreeView horizontal margin to 10px for tighter selection

highlight alignment with buttons. Replaced rotated right-arrow chevron

with two distinct icons: right chevron (collapsed) and down chevron

(expanded). Enlarged the chevron button hit zone to 24x24 min with

a subtle hover background for better discoverability.

Reverted New Page/Template buttons to original size. Added horizontal margin

to the TreeView (8px) so the selected item highlight aligns with the button

edges instead of stretching edge-to-edge. Filter margins adjusted to 12px

to match button padding. Removed unnecessary MaxWidth constraint on filter.

Reduce New Page/Template button size by constraining to MaxWidth 220, reducing font size and padding. Apply same MaxWidth constraint to the filter input. Wrap the page tree chevron icon in a Button with hover highlight and click-to-toggle behavior for expand/collapse.

The previous approach tried to remove "/" using EndsWith which failed

when the "/" was mid-text. Now captures the exact source control (RTE

or TextBox) and caret position at the time "/" is typed, then removes

the character at that precise position after the debounce fires.

Fixes intermittent empty quick action modals by moving QuickEventForm content

building from OnApplyTemplate to the constructor, matching QuickTaskForm and

QuickStickyNoteForm. All three form controls now implement IQuickActionForm

from the SDK, using RequestClose() to signal the shell instead of each plugin

independently using reflection to find CloseQuickActionOverlay(). This removes

duplicated fragile reflection-based close logic from Tasks (v1.18.2), Notes

(v1.53.1), and Calendar (v1.14.1) plugins.
