Tiny Bootstrap Elements Light

Sucks!! Just a bate

Default settings add only unusable buttons to Tinymce that tell you to buy the pro version; you have to go enable the free options, and you can't disable the unusable ones.
There is no way to edit the content of accordion panels, add new panels or tab buttons, etc.
It is impossible to add regular text after a bootstrap div if it's the last element of content without changing over to code view.
I didn't explore it thoroughly because it was a truly terrible experience in the first 5 minutes. I am glad this free version was available to test out, though, because I saw this first on CodeCanyon and was considering buying it.
