Thanks a lot! :)
Hm I hoped I had fixed that kind of bug in this version.. A combination of hitting the save button and reloading the browser tab might fix it though? I'll look into it some more!
The stacking to the right is definitely something that is unintuitive to many people, I am considering other solutions at the moment... Though I personally think it's nice once you get used to it and have a convenient way to scroll horizontally (middle mouse button, trackpad,..)
