Revert smaller tree/tableview headers
Reverts 1319a747
The header font size has become too small and I am not sure how font settings are specified, but perhaps some distros choose a variant which is smaller than other distros. For me the commit in question makes the headers very hard to read:
- Headers are not useless, they contain information that can be read
- I think it is better to be consistent with the rest of the world around the headerView for example the rows of the itemView
- Saving pixels in a headerview is not going to make a noticeable difference in the amount of space for the itemView rows to begin with
- It is not easy to figure out how to change this header font and make it larger. I can read the code and tell, but I bet a lot of users were just annoyed and couldn't do anything.
