Yes, a feature-rich sidebar is necessary.
Besides ChatGPT, what features do you want in the sidebar?

if possible, pin extensions to sidebar (or a block of buttons so that the audio playback button appears there in the sidebar https://i.imgur.com/CimRZXR.png )
vertical tabs (if it applies to the sidebar), because a lot of people bought widescreen monitors and now they have a lot of space on the side, and they almost all use vertical tabs
sidebar download menu, and merge with yt-dlp, so that when you click download a video, video download is sent to the download menu (I know it's hard, but I'd like to see it)
notepad with writing to local files
