I find it hard to justify the left sidebar’s being. I don’t jump around between servers, so most of the content of the left most component, I very rarely look at. This is the smallest I can get the left part when resizing it, made the whole window smaller, to see if that would get rid of it, but instead that removed the mid (server/channel) component, which I kinda need to switch channels, I do that way more than switch servers.
Did some crude copy pasting in paint, sliming it down and brought back the master volume slider, removed the left side, moved main app stuff like menu and settings button to the top. Have whatever was left in that component be visible when needed and hidden when not, some expand sidebar button or move it inside the menu.
