I have just started using Marketing Hub and have come across a few annoying problems:

1. Image library doesn't load thumbnails inside editor
2. 
   
3. doesn't change the text color of the pre-populated text in input fields (name, email, etc.)
4. 
   
5. Once selected a text Background, it can't be reverted to transparent, definitely needs opacity settings
6. 
   
7. Text border can't be reverted to "none" once selected either.
8. 
   
9. Can't edit 'Website Details' and 'Popup Response' settings once activated, not even when paused.
   
1. forced to clone and re-activate with new settings.
