Okay, I have to submit this update, because the previous one didn't satisfy me.
I reworked the whole app icons with the template from [link]
and modified them my way.
I added a new tab to the screen for my basic desktop folder setup. I think this one fits better my needs.
And I reworked the bowtie theme. Maybe I release it in a few days, but I had to work to the code. It's not smooth enough I think.
