Whenever I edit a post, the session expired dialog pops up after a minute or so. I can close the dialog for it to open again within a minute. If I cancel, I get redirected to the post, still logged in in spite of the dialog's remarks to the contrary.
I just installed the plugin with version 0.8.5 and haven't used it a lot, but the dialog did not appear in that version. It just started appearing with 9.0, and I tried updating again to 9.1 to fix it but the problem remains.
I like the plugin so far, and maybe this should be in a separate thread, but I have a request. For mobile support, I would like the editor bar to be three rows and fit within a 620 pixel width. I'd also like it centered with a top offset so it doesn't obscure my primary site menu which is fixed on top, but I imagine that should be able to be adjusted with CSS once it is modified to fit within 620 pixels.
