[Feature Request] A way to only show selected satellites

[FastThenLeft]

When I'm in the satellite selection window, it would be nice to have a way to quickly toggle to only show the satellites I have selected.

As it currently works, I have to scroll through a long list of potential satellite selections to see the ones I have picked.

Hey there and thanks for raising this! The satellite selection topic is extremely difficult to get right and please everyone. I keep getting emails with various conflicting requests and not sure who's opinion to follow. So I'll be following mine =)

I know for sure, that many people find categories to be very misleading. As the categories data is not present in Orbital data itself (TLE, OMM), it's fully synthetic, derived from Celestrak's lists. So the categories will soon be disappearing from the Satellites page. With this change all the satellites will be displayed by default, this will make it easier to search without switching categories.

Initially I plan to replace the categories dialog with the Modes selector, just so it's possible to quickly identify the satellites of interest. However later the whole page may be revamped to achieve the "seeing the selected satellites" behaviour. Also to get this feature to work correctly the select all / unselect all buttons may be gone.

I have several ideas about how to revamp the satellite selection screen, I need to build these variants and see for myself what makes the most sense. I also had in mind a few features like selection export/import, so people don't need to waste time.
