NEW EXTENSION: EDITABLE REBLOGS
Tumblr made a stupid update, I made an extension to fix it. We’ll need to update a core XKit function before it works for HTML and Markdown users, but it’s a start. The extension should be available momentarily.
This is greatly improved in version 1.0.7. If you don’t have the version we recommend to restart your browser and click the “update extension” button for Editable Reblogs. It still doesn’t support HTML/Markdown as a default editor.
