> This is extremely well done design (at least on full desktop browsers).

I can't tell if you're being sarcastic, but on my full desktop browser the side bar overlaps the main panel, putting text on top of other text.

P.S. Other than this, I do like the presentation.

It looks decent on my 1920x1080p window running on a 4K monitor, but I have overlapping problems on my M1 Macbook.
