Total Commander

Hi.
Can you add ability to change bottom button bar?
I never use button pack file but it takes up space it would be great if I can replace it with button rename file e.g.
On the bottom panel, we have 6 buttons and one blank, while on the top panel in my case there are 15 buttons.
I need to make a long slide to reach the last button, while the bottom panel remains empty.
It would be great if i have option when creating a new button to choose where I want to place it bottom or top.
And the ability to move standard buttons on bottom bar.

Currently you can only decide whether you want to put the user button on its own button bar, or show them behind the 6 default buttons. I don't know how to handle this better because the available space is very different in horizontal and vertical mode.

All that I wrote above refers to vertical mode, and in horizontal mode everything was the same as before.
Can you at least add an option in the settings that fit the width of standat 6 buttons in portrait mode, or maybe one adition button to fill empty space on bottom bar?
