Wow, DDDot is great! Basically, combining DDDot and "Control+P" for searches, I could keep the stock side panels almost always collapsed. Also, I've set DDDot to collapse with F9, so it's only one shortcut, instead of two, to go to full editing view and back. Only the sync info would be missing from the view.
Only thing is... do you know a CSS code to force the width of the DDDot panel? It does not seem to remember the user settings when toggled back on after a collapse, which is unfortunate.

I've tried the following without success:

.resizableLayoutItem.rli-plugin-view-joplin-plugin-dddot-dddot\.panel {
    max-width: 250px !important;
    width: 250px !important;
}
