Usability improvements for mobile app - list views

[DovAmir]

many users have a list of DSO's that I want to focus on and require the following usability improvements.

1. option to show/highlight in the night skai view, all the objects in the list with its name /label.
2. Allow creation of multiple lists (currently I can only create 1 favorites list)
3. saved lists/filters - allow to save a list/filter like for example "show all galaxies, that are in my favorites, and are currently visible". This will help users get instantly their desired view, and they wont have to choose 3 filters every time.
