Recently updated from v14 to v17, have a couple questions

I’m using v17 beta 6

1. Add-ons, is ‘install from zip’ broken? I want to install another repository by zip file but no menu comes up

2. How can I enable keyboard.xml from here? HOW-TO:Use_SMS-style_text_entry_for_remotes (wiki)
I’ve read ‘Remote control sends keyboard presses’ is enabled by default, but this does not work

That’s all for now, thanks!
