As requested in #277 by Devin. I mark this as a draft because there are small issues that need to be fixed, but 75% is working right now.
- [x] Adding connection works
- [x] Loading existing connection works
- [x] Update existing connections works
- [ ] Show updated list of profiles without restarting the kcm
- [ ] Find a way to use that in initial start (because the whole software is going left-to-right, so pushing an edit page to the right might not be intuitive)
I'm still wondering if using checkboxes for 4G/3G/2G might not be better.
In NetworkManager, there is a global "wwanEnabled" setting. We do not typically deal with this because toggling it off shuts off cellular in ModemManager (the mobile data toggle just disconnects the connection instead).
Here we ensure that we address the case when "wwanEnabled" is off, and ensure that it's on when mobile data is toggled on. Also remove a check in the SIM page that seemed to depend on it.
This (partially) reverts commit 127bbdf653.
Only incorrect changes from Kirigami.Units.largeSpacing to
Kirigami.Units.gridUnit are reverted. Only Plasma.Units were buggy.
