Hello. I would just like to make a suggestion for export option of skeletons.

Now, you have to click separately on each skeleton to see if it will be exported. I would recommend a symbol or mark next to skeleton's name, so you can see which skeletons are going to be exported, without clicking on them.

And another thing, option of selecting multiple skeletons and checking/unchecking export option.

Thank you, have a nice day,
