Choose allowed extensions

Hi !
thank you for your really nice plugin, which will save me a lot of time !
I just would like to ask you for a simple feature : could you please let in the settings of the plugin, choose the file extensions we would like to allow please ?

I saw in the plugin it was hard-coded, so I can just change it in the plugin for now, but I would like something more update-proof, such as a filter on the allowed extensions list.

I wanted to prepare something like that to push it to your github, but wasn’t able to find your repository …

Thank you already for reading me ??
