Change Left Menu Column Width

[ChessCoin]

Hi all,
I'm new here, and first I'd like to say Well done to the team behind EspoCrm!
Quick first question: how can I change the width of the left column menu? (I'm using EspoCrm with sidebar template).
Also, how can I change size of the logo?
Thank you

Hello,
for this I recommend you to develop own theme
