Changes
- User-locked app windows #872:
- Add a toggle next to the AlwaysOnTop toggle in the window menu.
- Prevent drag-and-drop actions for non-owners.
- Block input focus for non-owners.
- Restrict taskbar operations on locked windows (Close, Close Group, Pull by Alt+DoubleClick).
- Prevent server shutdown if locked windows are active.
- Fix redundant (spam) mouse move events in DirectVT mode when UI updates are absent.
- Refine UI tooltips for better clarity.
- Allow omission of the vertical bar operator for quoted substrings in DynamicXML settings.
- Abort server shutdown if any user has a window in fullscreen mode.
Now users can lock windows, restricting access for other users.
Everyone who was focused on the locked window at the time of locking becomes its sole owner.
The restrictions set prevent the desktop server from terminating.
