I have encountered a problem where I can't seem to stop GhostText add-on from syncing with my Sublime Text. But later on I found out that if I close the GhostText tab in Sublime Text directly than the connection is closed. Instead if I leave the tab open, but click on GhostText button in the upper-right corner in attempt to turn it off, the textarea will stay blue and the connection is not closed.
Takes a little more to setup than most add-ons, but if you type a lot of text or code into website text fields give it a go.
I used this to help fill out an EU consultation and it worked a treat. Those forms have dozens of pages with teeny text fields, and integrating Atom not only was more manageable, but had my dark theme and installed packages too!
I have been using ItsAllText on Linux with the Emacs editor for a long time. When this extension became unsupported, I started searching for a replacement. I am happy with GhostText, which works well enough. Note that Emacs requires atomic-chrome in order to work with GhostText. Thank you!
I didn't give 5 stars because sometimes GT gets a bit confused and the editor unsyncs from GhostText. But it might be a problem with the editor extension.
