I think it is okay to implement a Blur Layer and use Gaussian algorithm for all types of blur. I think this is acceptable approximation, since blur is used often.
Thanks for letting me know! Google recommends to adjust timeline according to changes. It is possible to start coding period earlier and add a gap for exams. Let’s wait the moment when the dates of exams will be known.
I can see that some items from proposal timeline are not reflected in milestone.
So, as first step, I suggest to transfer all items from proposal document to milestone.
Then, we will need to align milestone items with evaluation dates (define which items are mandatory for evaluation and which are optional). I think the best would be to write this information as a subpage here - https://synfig-docs-dev.readthedocs.io/en/latest/projects/lottie-export-for-web.html.
