Is there a way to drop windows down into a taskbar in GNOME, then later restore them by clicking on the entry in the bar?
The Windows operating system, as well as some desktop environments in Ubuntu, but not GNOME 3, have a panel called the taskbar which contains a window list. Application windows can be minimized (iconified) and shown only in that list, then restored by clicking on them in the list.
Is this possible with GNOME Shell in Ubuntu 17.10?
There's a much easier way than editing config files - simply add Pixel saver extension to get rid of the title bar and reclaim your screen space.
It has the added benefit that you still get maximise/minimise buttons but these are now stowed away in the top panel.
I previously used Maximus but this seemed to break with gnome 3.8 - Maximus also use to give me issues with pop-up calendars for my bank but this extension play nicely with that too.
You can auto-hide the Ubuntu Dock by going to Settings > Dock and the toggling on "Auto-hide the Dock".
If you wish to have a pure GNOME experience, follow this Q&A: How do I get a vanilla GNOME after Ubuntu 17.04?
Best Answer
There are some GNOME shell extensions which may help you achieve this goal.
It displays a list of open windows at the bottom of the screen. You'll be able to minimise and restore windows by clicking on the window names.
It's a modification of the Window List extension. It displays a list of open windows at the top of the screen and offers a few more customisations.
