Auto save after deleting components

MIT App Inventor Help
1

I was deleting a component in the designer view but accidentally selected the wrong one (HorizontalArrangement). After confirming the delete action, only then I realized I deleted a group of components. I tried undoing the delete action but unfortunately there is no undo for component delete. I was thinking, I can still restore it by closing the browser and logging back in but no luck. Sure I can still reconstruct all the blocks arrangement but the effort and the time I lost I cannot take back.

Is there a way to undo component delete action? Can we disable the project autosave after such action?

Thanks,
milan

Welcome Milan

No and No. :frowning: You can do what the PUs do and frequently save an aia. Then, when you can not back out of an action, you can revert to a condition fairly close to where you left off before your mishap. Developers can also save a copy of their Project ... save as...

You are not alone, we all have done something similar. When working with lots of arrangements, it is frequently prudent to make an aia prior to trying to rearrange the components as adjusting arrangements can get tricky.

The Project autosaves once ever five seconds. Are you that quick that you could recognize a mistake and exit? Sorry...that will not work.

Thanks Steve, lesson learn for me. but would still encourage App Inventor developers to add such features.
