<d_ed> Riddell: yes and no. Needs doing, someone on Plasma the other day wanted a task, so I helped get him set up with that

FWIW, I wanted to work on this a while ago and @hein said this would be looked into by his GSoC student. Maybe it's a good moment to review the state of this issue.

@apol My GSoC student has used this code as inspiration, if you look at the review request for his work, his version of kimpanel now has layout indicator support superceding this one here.

You're saying "this one here" as if we had one. Now we don't have anything.
Which review request is it?

Probably this one: D14796: Port Keyboard input modules and Expand scope to cover input method configuration

Yeah, it's that one.

You're saying "this one here" as if we had one.

I thought this URL was your merge request for your code, sorry. I didn't realize it was a task ticket instead. Phabricator is a bit confusing sometimes.
