Click + drag to collapse sidebars

[nth-chile]

Describe your feature request

• If sidebars are resized past a min width (30px?), hide them, like VSCode
• If both sidebars are visible and you click the right edge of the note list and drag to the left, you should be able to hide both of the sidebars. First the note list collapses and then you're resizing the sidebar, and if sidebar gets small enough it collapses too
