How do I get the last action back?

[Lexus2016]

There is a situation when after placing Meraki UI - Navigation (Last block) there is no button to delete or move it. I add other components - there is a button on all of them, but not on this one. I had to completely reset the project and start all over again. How can you solve such problems? Where is the file with the configuration of what has already been done?

@Lexus2016 Thanks for reporting.

It's not exactly a configuration but an HTML file and it's located in data/default.html.

If you can reproduce the problem maybe in the form of a screen recording I could have a look further into the bug.
