I'm moving from Mac to the amazing new 20.04 Ubuntu Mate, and thrilled! After exploring some of the other great Themes and options, I settled on Cupertino. Along the way I liked some of the top panel applets in other themes, and couldn't find them in the Cupertino or Contemporary themes. After considerable effort, (guessing the options were "in here somewhere!") I found a trick and am now enjoying several new (apparently old from prior versions) applets.
When I right-click on the top panel, the handy "Add To Panel" option that's in nearly all other Themes doesn't work. I just get the sparse new Preferences list of options. I of course dragged a few useful things to the top panel, but those other applets (like the Clock w/seconds, day & date) were nowhere to be found. Some of the Add To Panel options are uniquely great. To see what I mean, here's the simple Trick I chanced to find:
- Right-click on the left-most item on the right side of your top panel.
- Make sure "Lock to Panel" is NOT checked, or UNcheck if it is.
- Click "Move" and drag that item to the Left, to open up some space.
- Now right-click in that new top panel space you just created.
For whatever reason(s), the familiar Add To Panel option only works in an open area anywhere to the Right of the Left-most top panel item. That area also gives you access to the handy panel Properties options like Size, Hide, other Panels, etc. So I've found it useful to maintain an open area somewhere on the right side for future tweaking.
I'm greatly appreciating all the work that's gone into this slick and quick OS, and hoping this tiny trick may be useful to others who find their way here.
