Save button disappears

Hello all!

I just downloaded this plug-in yesterday. I haven’t yet explored it thoroughly, but I have noticed a couple small concerns that I will need some clarification on:

1) After making several rounds of edits & saves to a test popup, I’ve noticed that the “save” button (in the upper-right “Publish” box) just disappears. This is a problem because I’ve made changes, and don’t want to lose them. I also don’t want to publish it just yet.

2) Is there a way to PREVIEW your popups without actually publishing them live? I can’t seem to find a way to do that.

3) I’m new to this, so please forgive me if this is a simple fix but, why do I only have v1.3.3 if I just downloaded this? I noticed on the dropdown within this comment tool that there are version in up to the 4’s.

Thanks!
