{
DO BEFORE RELEASE:
DISABLE ReportMemoryLeaksOnShutdown in project's .dpr
Change build configuration from debug to release
Update readme
Update version string in uDiskEjectConst
Update version info in project
Jedi API - change compiler def to Win2000 and up
JwaWindows - check which version its pointing to - release/debug static/dynamic
}
{
TODO:
OTHER:
For grouped drives show mountpoint/drive letters somehow
Cant tab to the move label on main form
Optional/Possibilities/Non-critical:
See mindmap for full list
Timer for ejection? - eg if running from pstart menu - run command to eject stick in 5 secs - gives time to close the menu
Intercept shutdown/restart message and warn that usb stick is still in the drive. Dont forget it.
REMOVEALL switch - eject every usb drive it finds?
Hide certain drives when specified by user?
Use new Delph 2010 hints for all controls in options
If restarts in mobile mode and eject fails - load main app back up again somehow?
Customise what is displayed for each drive? Icon, colour, label etc
Hotkeys - need to know when restoring from ini - rebuildhotkeys - if hotkey active or not + to show this in options
Localisation
Card readers possible alternate detection? Use same method as windows rather than polling - is this available on all versions of windows though?
