[WIP] Make tree new file link more visible.
Created by: cirosantilli
- I remember the first time I wanted to create a new file from the web UI searching for the button. It's harsh on new users.
- every time I want to create a new file I have to concentrate to find the little
+. - more coherent: GitLab uses "plus sign
+text" green buttons for all "create new thing" links, including the analogous wiki "create new page" button that also adds a file to a Git repo.
This is just a mock up, I'll improve if people are for it.
Main difficulty: to look nice the button has to be as high as the branch dropdown to its left, but buttons are larger than dropdowns. I wish buttons, text fields and dropdowns all the same height. Analogous UI problem on the /network tab due to different heights of search field and dropdown.
