This is exactly what I need, and now I use this extension almost every day. I have a small suggestion: I need the functionality to reopen the SideView content in a new tab, or the ability to copy the current SideView content URL. Thank you for your contribution.

Thank you, this is the feature I wanted.
However, like Yandex Browser, Whale Browser, Edge Browser, and Vivaldi Browser, closing and opening the window does not keep the content displayed.

Essential plugin that I can't do without anymore, thanks for the fix Google meet! Would it be possible to have this extension for ff mobile?

This is perfect for quickly throwing an email I am referencing in the sidebar and copying the data over!
