Thanks for sharing your thoughts and feedback 🙂
Some of the points you are mentioning will be fixed/improved in the next software upgrade (V2.0, planned on July)
One of the big problem for now (V1.1) is that you can’t cancel a sequence, or run a part of it. In the new version (V2.0), you will be able to cancel a sequence, and create separate functions, so you can have all your blocks on the screen and only call a specific part.
About the copy/paste functionality, unfortunately this is not (and this won’t be) possible to copy/paste multiple blocks (technical reasons). But with functions, you will be able to create a bunch of blocks, and then copy the function call, so this is a nice workaround.
