A small follow-up to the sidebar sections in v0.8.0, for the two moments where the sidebar knew what you wanted and made you go and find it anyway.
Sidebar
Edit property. Hover a section header, click the settings button, and the menu now offers Edit property above Remove from sidebar. It opens Custom properties with that property already selected — options, colours, and the Show in sidebar switch right there. For Tags and Board it opens their locked built-in pane.
Configure sidebar. Remove every section, Tags included, and the middle of the sidebar used to be blank with no way back except More → Custom properties. Now a Configure sidebar button appears in that space whenever the pointer is over the sidebar. It opens the same dialog, and it disappears the moment any section is showing again.
The properties dialog can open on a property. Both of the above use it, and so will anything else that needs to send you to one specific property. If the property has been deleted in the meantime, the dialog falls back to its usual first row instead of opening empty.
Worth knowing
The configure button is deliberately invisible until hovered and only exists while the sidebar has no sections at all. If you can see it while a section is showing, that is a bug.
