Large files left hidden on my hdd and unstable

I like the idea of the app.. but I noticed it leaves very large uncompressed files in the following folder…
/Users/UserName/Library/Containers/io.quickcast.QuickCast/Data/Library/Application Support

And it also seems pretty unstable. I’ve been trying to force-quit it for a while and I guess I’ll have to reboot. I tried to create a video and then went to click the Stop menu option and there was only a Record menu option… but it was already recording! Something got out of sync and now I have to reboot. Lovely.
