Built on top of scene2d is a UI library, now this might actually be something you want to use if you game needs a complex UI. It's easy to sink a lot of time into making yet another a UI framework so this could be a good productivity boost.
I've been using the Scene2D UI for a lot of my UI stuff and it's been working well so far. It was a little tricky to figure some things out due to poor documentation, but I got it working.
You'll have to assess how well those future features map to the scene2d approach and what the alternatives are. If you think you'll roll your own exact equivalent then you might as well use scene2d. But if you think you need more/less then perhaps some other solution might be more appropriate.
The main thing I was thinking of that it would make easier would be how my game handles input. The game is tile-based and whenever you mouse over a game object, it should display what the object is (as well as a default action to perform on click) in the top corner of the game. I'll also need to add in right-click option boxes for items and game objects. For example, if you right click on a person, it may list: Talk to person, attack person, examine person, etc.
On your repo page there should be a cog/gear icon for settings on the right-hand side of the page, near the top. Within the settings there's a tickbox to say whether the repo is public or private.
Oh that was quite easy, thank you. This is my first time using version control, so that helps a lot
