Collapsing the Vivaldi Tab Sidebar
tl;dr: In Vivaldi, middle clicking the separator between the tab sidebar and the web page will either collapse or expand the sidebar; when collapsed, it shows just the tab favicons, and the workspace selector icon.
If you want to know how I got to that point, read on.
Diagnosing Vivaldi resource usage
I recently noticed my CPU usage was high, and it was due to my open Vivaldi browser. I wasn't sure what tab was causing the issue, so I searched to see if Vivaldi had any tools for reporting this.
It turns out that Shift-Esc will open a task manager, and you can sort on any of:
- Task (a string representing high level things like the browser as a whole, GPU process, worker tabs, and more)
- Memory footprint
- CPU (this was what I was interested in!)
- Network usage
- Process ID
You can select any task to end its process.
I was able to quickly track down the issue to a background worker running for a PWA window I'd closed earlier, and ended the process.
