It seems to load the FBX from whole folder, not just selected. And I need to select just 1 FBX, otherwise it is giving error. Overall an interesting addon and making importing animation and remixing them much more natural! Thanks this is a great buy!

Thanks for the feedback @enzyme69. v1.0.4 will bring a lot of refactoring on that feature. As you mentioned when joining animations, it fetches all files in folder, so there's no need to select them individually as long as the folder contains all animations you want. Regarding NLA tracks yeah, there seems to be an issue on the export not considering the first track, right now the most used exporter from our community is the better collada as there's no additional setup on NLAs to work with it.
