Have fun with the library!
Why is it in German?
And speaking of which, why is your name SoonGames? Are you a company?
No. Only the preview is here in German. It is in English with templates, so you can customize it to any language.
I am not a company yet. No.
That's one of the first things I did; except I indented the nested inventory items with unicode box drawing characters.
Good to see it as a proper library.
I just contributed to a game in which we used a similar method!
Yours looks better, though, SoonGames! We'll probably use this next time (and credit you, of course).
