Highlight files with colors / checkbox column

[KranichIbykus]

First of all, thank you very much for this tremendous and awesome browser, I cannot imagine a life without it, seriously!

I would love to have a feature to highlight or mark files. The optimal solution would be to be able to underlay files in the folder view with various colours. That would help me immensely at work to know which files from a list I've already finished working on/checking.

Alternatively, this could also be done by having a column with a checkbox which you can tick. (Which I believe doesn't exist either.) But the actual highlighting of files would be a lot more useful. That way, you could for example say: Green = Already finished; Orange = Needs rework; Red = Needs to be completely redone etc.
