Plugin support & Editing transitions

Hi, fellow Hitfilmers.

I have a quastion to Hitfilm Express: Is there a Plugin support and if yes what kind of plugins are there?

And a second question, or rather a suggestion is: Can you add a feature, where you can edit the length of more than one transition, if you have several selected? (just like with the clips: if you have several clips selected, you can edit their length all at once)
