if I want to install all of JackDole's add-ons at once, I can now do so?
Well, we should wait until JackDole upload them to workshop. And I assume that you have to subscribe every of them one by one.
I also already like HarbingerDawn's "E-Wing Cockpit"- can I use that as the default view for all my videos flying above a planetary landscape or in outer space?
If HarbingerDawn didn't change file names, SE will load the most recent ones (from the workshop folder). I suggest to delete his old addon from the addons folder and use the workshop's one, because that version may be updated sometimes.
Vladimir since you are here, I was wondering if a small addition could be made to the program to show compass points, so one can tell what direction they are moving on a planet. (N,S,E,W). Or alternatively, you could just make a small compass in the corner of the screen with a pointer showing what direction movement was occurring in. In addition to that, HD could add a compass to his cockpit to show the direction of flight with a pointer.
