Sorry that the new website format has made it difficult to locate some older posts.
Unfortunately, I can’t give you any estimated timeline for 1 and 2 as these are much more involved projects. However, we are currently in the process of looking into 3 and some other improvements to Scenes. I’ve also made your copy/paste request a higher priority that we will look into, and while I can’t make any promises, that request would be more likely to be added sooner than 1 and 2. Thanks for your patience and feel free to let us know of any feature requests you may have.
