Hi Csaba,
The tabs functions are great (attachment).
If you have maybe some time, there is some room for some more improvement.
e.g. TC has the next right-click menu on the tabs:
################
Duplicate this tab
Rename/Lock tab
Lock this tab
Locked, but directory changes allowed
------------------------
Copy tab to other panel
-------------------------
Save tab to file
Save tabs on both sides to file
Load tabs from file, keep current
Load tabs from file, replace tabs
-------------------------
Close this tab
Close all tabs
Close duplicate tabs
################
Thanks and bye,
Frank
