If the list is already kept in a memory, my proposition isn't very 
attractive. I've updated from 2.1.4 to 2.1.5 (it was a long time ago 
when I was using 2.0 branch, but you are probably right that EasyTag is 
now faster) and there is still some delay. Its length depends on number 
of songs in the current directory. It's about 0,6-0,8s for ~300 mp3 
files. I noticed that even for directory with only 3 files there is a 
small and completely acceptable (but still visible) delay, so maybe it's 
time requires to refresh/update widgets in GUI?
Another reason could be that my computer isn't very fast - Athlon XP 
1,8+ (~1,5GHz). I will try to test on Intel Core 2 Duo 2,2GHz for 
comparison.
