Wow, that is a great character animation! Mind if we potentially use it in our gallery?
I'll try to answer the questions that haven't yet been addressed:
This is an artifact of how SVGs are represented in the browser when inserted as images. There might be a way around it using a scale factor, which is what we'd do for symbols:
We definitely realize this is a big missing feature 
.
Hype uses integral pixel values, which can cause jitter if moving very slowly. This is mainly for browser compatibility and performance reasons, but it has been a while since I re-evaluated the landscape and might take another look. Generally if you use linear timing functions it will reduce the apparent effects.
Thanks for this feedback.
Hype uses per-property keyframes, so there's really no single keyboard shortcut that could work in this case. I'm curious how using the Record (which will automatically make the right keyframes) won't work in your case?
Good idea.
I think we'd need to develop some macro system. Can you elaborate on the resume timeline action though? If it is paused the playhead would then not ever hit the resume!
As mentioned this is command-option-e, so you might have it overridden by something else?
Interesting idea.
