I'm very glad for this extension, and it works well. Good work! However, there is one issue: on certain sites, the text boxes have buttons in the lower-right corner where this add-on puts its own "Edit" button. In some cases, this is a "Post Message" button, and when I try to click on "Edit", my message gets prematurely posted.

It would be helpful if one of the options for this add-on would be for us to override the default location of the edit button within text boxes.

I know that I can still edit using the button in the toolbar, but it still would be desirable to be able to specify a different default edit-button location for text boxes.

It would also be desirable for this add-on to optionally launch emacs with a specific environment variable or command-line option, if it doesn't recognize any existing emacs sessions with `edit-server` running. I could write emacs startup code to recognize this environment variable or command-line option and if it appears, to then launch `edit-server` within my startup code, so that it could be used within this app.

But again, good add-on, and good work!

Maybe not production ready for everybody - but a value productivity enhancing addon for the advanced user.
