[Feature request] Completely customizable bottom generic row

Currently it’s only possible to select bottom row layout from a fixed set of options. It would be great if, instead, it would be possible to edit bottom row by adding/removing desired keys in desired order. I’d imagine it would work like, for example, desktop toolbar editing:

[     area to be edited with selected keys      ]
-------------------------------------------------
      [key1] [key2] [key3] [spacebar] etc…

Adding/removing would happen by tapping on keys in section; adding new key to layout would locate it at the end of the layout. Most keys would have fixed width and [spacebar] would be flexible and would occupy remaining space.

This would be a great feature. It would also be very useful for those using a dvorak layout where ‘.’ and ‘,’ are placed among the letter keys and thus redundant in the bottom row.

@menny any progress on this? Many of us would really like this feature (this issue has the most “likes” on the repo)
