Description

for more user friendly use i think is need make some changes, i have some tips:

1. show available unmounted usb devices like usb flash disk... (currently is not removable show if not mounted)

2. use only left mouse for mount and if disk already mounted for open via Thunar (or app selectable in settings)

3. unmount only with right mouse button (or show context menu for right click with: mount, umount, eject, smartinfo(?), $usercommand('s))

4. if lists is empty, show one info line with some like "no any disk's in list" (instead 2mm small line as now)

5. for more user friendly settings: show clickable devices list with checkbox (with remembering devices not curently avaiable (with posibility of selectable remove, aka trashcan icon next to checkbox?) and/or option "Show only removable devices(this will be auto disabled mountpoint like /, /home, or system mount/bind used in fstab, than in many case is not need available for unmounting"

thanks for read this, and think about it ;-)
