In classic, you could select multiple clips at once and adjust the clip speed. This is no longer the case in Storyboard, and it would be helpful to have that functionality restored.

It would be cool to create a template for things like Fancy captions so I don't need to adjust them every single time in terms of size, font type, border, live text, etc. Or section headings, the same thing. I spend a lot of time doing the same things over and over on a different part of the script.

Convert sequences into multicam clips when doing a Timeline Export to Final Cut Pro or Adobe Premiere

Apply your own LUTs to visuals in Descript.

These would be really handy

I want to be able to see my files in a panel on the side like in classic mode. It's awful to have a lot of files in a project that I have to view in a drop down menu. I want to be able to make some panels smaller than I'm able to now or even make them disappear entirely while I'm not using them to save screen space. I want the toolbar on the top again for things like Markers, Ignore, etc. Classic was so much easier to use in my workflow.

For ex. breathing and laughter should be tagged as such, and not be treated like gaps. You'd also be able to search tags to find all instances of applause for example.

Allow easing of animations in/out/in & out.

Make the new Timeline better in in the little ways that add up to it feeling like a good and usable timeline.

Ability to perform J/L cuts by offsetting audio and video on the script.
