Please have the option to make things smaller.
So often, fonts are too large, object too big, taking up too much real estate on the screen. For the Board/Kanban board I can only see 4 columns, keep having to scroll left, right, left, right.
I like to fit a lot of information (color coded as well with more detailed info displayed) on the screen. Current size of buttons look like clown shoes.
For a good example of what I'm talking about see Trello's KanBan board. Lots of color, data, info, and much seems to fit on the screen.
