With 4.2.0 beta, MyDefrag doesn't update display with every file moved but rather periodically, several times per second. I like it, but when it is moving number of small files I can't see what has happened in the past period, it only displays current state and current operation.
My suggestion is, MyDefrag could remember all moves it did between screen updates and display them all (in disk map only, status lines etc would still only display current file).
And it'd be also nice if it remembered current operation (which part is being moved where) and redisplayed it on zooming/resizing.
I know it is only minor thing, few people even look at the window ... but it'd be nice to have
