Available addon updates - combined count badge

[Daeveren]

Is your feature request related to a problem? Please describe.
The count badge showing how many addon updates are available combines the available addon updates for all the wow installs. It shows both at the top of the app

but also in the taskbar

The problem is that all these 5 updates are for 'other' WoW installations that I only play sometimes or very rarely. But I do play Retail as main game and check for addon updates multiple times per day, everyday. Having the badge up both tricks me and also makes me excited :) believing I have addon updates for Retail (I love addon updates), but proves out it's about Classic or Classic Era.

Describe the solution you'd like
A way to only have the badge (both at the top of the app but also in the taskbar icon) show up only for the main game that I play everyday. I could see this doable in a few different ways, but surely there are several other ways of doing it:

1. Have a per-game toggle in WowUp Options that would enable/disable the addition of addon update counts for each WoW install into the 'main' badge count;
2. Change the default counting behavior of the badge so that it would only show the currently selected WoW install;
3. Add a toggle in WowUp Options "combine the addon updates for all WoW installs in the main badge"
4. Disable the 'auto check updates' for all games at both WowUp startup and periodically - maybe only leave it for the currently visible install

Describe alternatives you've considered
For Classic Era I have considered setting WowUp into automatically (and I hoped, invisibly too) updating all the addons - but at this moment the feature does not particularly works for my install. Even if this feature worked, there's the issue of WoW Classic which I would preffer to not be shown the updates badge but I would also preffer to not have auto-updated (I like to do manual updates so that I read the change logs for each addon update).
