5.2.0-preview01

Bonjour, c'est la preview.

Preview release because it's been a while those new features were implemented but never released. There's another one I'd like to tackle before making this stable, but why not getting some feedback on those already?

Here's the cool new stuff :

• As suggested by mhusinsky in #57, you can now temporarily mute package repositories and editable packages. This allows you to disable some of those without having to delete and re-create them later. Pretty handy indeed, thanks to him!
• Thanks to bj-rn, the launcher can now be minimized to the system tray, yay! There's a new App Settings section in the Settings to enable this feature or not, you choose.

The mute button feature introduced some breaking changes in the settings files. There should be no problem though, as the launcher should be smart enough to translate from "old" settings files to newer ones. So please :

• Backup your settings files just to make sure if you really care about them (reminder : CTRL + , to open the settings file location)
• Report if something goes wrong when going from last stable to this preview

The last feature I'd like to implement before making this stable is about being able to download stable releases from the launcher. It should now be easily doable, let's see..

Enjoy!
