Being able to readjust the sidebar

With the new update came with a very ugly UI design, but that is merely subjective. 

What became an issue is that server icons are now minuscule and hard to read/see any of the detail that the once had before. As a person with bad eye-sight, this becomes an issue with distinguishing what server is which. The new UI density options do not even do anything to negate it, only changing a feature's size by maybe 1 pixel. 

I'd suggest being able to readjust the sidebar ourselves, rather than having to rely on set configurations that are provided.
