still unable to quit the program (Linux Mint) and libraries still missing
I forget to fix that, i will fix that in the next release.
The Snap! source code on GitHub uses the file picker to pick libraries, so you'll have to download them then import them.
I think the libraries folder should be in the downloaded folder.
I've found I can close the program by doing a File New before exiting
That is not the fault of @mrdev88. You must be running your instance of Snap! in a webserver for the libraries to work.
I don't mind loading a library using a file picker but they have not included the libraries folder so there is nothing to pick
I will upload the libraries folder to github
