can't get rid of columns Ohodnoceno 3 z 5 hvězdiček

I rearrange my columns, exit Yoono, come back, and all the changes are not there anymore.

moving columns Ohodnoceno 5 z 5 hvězdiček

is hard to move a column in between 2 others. maybe 2 small buttons, one for LEFT and one for RIGHT on top could help.
