1. Since b1379 there are two file cursors - in each file panel
2. Since b1379 hovering (file cursor follows mouse) works for inactive panel too. In earlier builds it worked only in active panel.
3. There is a bug with cursor following mouse pointer (hovering).
a. Set small wait time (20 ms)
b. Create quicklaunch button which accepts files as parameters (e.g. notepad)
c. Drop some file(s) to that button
d. Close application (notepad)
e. Move mouse to MC but don't click, then move it over files/folders
Result: cursor following for active tab (from which files were dropped) is broken. Wait time is not 20ms.
f. Now click on the Explorer panel.
g. Move mouse over files/folders
Result: cursor following is restored. Wait time is 20 ms again.
4. Changelog says that SetActiveTab support /PREV /NEXT params, but they are seem to be missing in custom commands
