Save dialog before leaving pages


I love using and adding new skills to rhasspy. Thanks for the hard work of all project contributors.

Regarding the UI I would like to make a proposal.

At the moment in case you’ve changed something at different pages (sentences, slots) the ugly default “leave page” dialog of your browser pops up.

Wouldn’t it be nice to have a proper save dialog rhasspy like?

What do you guys think?
