Some days ago I set to memory to read-only. Now I have the impression that CafeTran sets the read-only attribute to my memories randomly.
However, there is some room for improvement:
A hint after opening files/projects when there is no TM writable
When executing "Memory > Import > Import segments from project", there should be a hint instead of a empty dialog box.
A very small visual indication that a TM is read-only (somewhere in a corner of the pane, or even in the segment when using the Matchboard) would be a nice thing. This could be an asterisk, a colored line or sth similar.
