Is there a way to force an application window off the screen?

For instance, the Cisco AnyConnect client is a constant companion of all my apps, although I will NEVER need to alt-tab to it, or need it after I launch it in the morning.

Hipchat client is the same way...it wont "iconify" to the system tray like Slack does.

I think this is on the app developers to implement, but can the desktop windows manager make it happen, too?

Moving the app to another workspace isn't ideal for my work flow, but that's how I manage it until I can find a better solution.

You should be able to do that with Application Rules:
Right-click the titlebar of the application -> More Actions -> Special Application Rules
This will bring up a dialog for you to confirm the matching rules and set up what you want KWin to do with any matching windows.
Under the Arrangement tab you can check options for Skip taskbar, Skip pager, and Skip switcher.

(If you mess something up and need to pull up a window that you can no longer get to via normal means, you can get the window back by pulling up the dialog via System Settings -> Window Behavior -> Window Rules and adjusting the options including forcing it into an on-screen position)

Just another in a long line of why KDE is my new favorite thing!

thanks...worked like a charm.

Yep, agreed.

KDE might be a bit of a resource hog (but who cares, with modern machines having plenty of memory), but, Lord, it's so versatile and configurable, it's ridiculous.

When I started using Linux I took a few days to test each available DE.
KDE seemed the best choice then ... and I've never looked back.

Nowadays I don't even bother following improvements or updates of other DEs. If one familiarises oneself with KDE properly, there are very few things this DE cannot do.
And the utilities that come with it (Konsole and Kate kick butt, Dolphin and Konversation are good) allow a quick start without much changing of apps.

The only two things I personally don't like are Apper (removed it, since I use the terminal for package management anyway) and Discover (which is horribly cumbersome and totally unnecessary).

And once KAccessibility has been properly "disarmed" and doesn't make a nuisance of itself every few minutes, KDE is sweet.
