I would like to make 2 suggestions concerning Double Commander's GUI :
1) it would be nice to have the columns width saved when leaving Double Commander : it looks like, each time Double Commander starts, it reckons the adequate columns width. I would like to use my own columns settings
2) in my humble opinion, the clearest the GUI is, the better it is : therefore could it be possible to "withdraw" the frames/lines separating both panels so as to have a less "cluttered" interface. The screenshot below indicates the target area :
Thanks in advance and keep up the great work !
