After compilation, there is a adv link (>) and a Close button.
As I would like to see the related adv, I was driven to its page, but I lost my Kodular workspace.
I suggest to open a new tab in case the user turns to the adv.
I know it’s easy to say now, but it’s important to manually back up the project after every substantial change, unfortunately people often realize their importance the bad way
Clicking the adv button I was transfered to this site, expecting that the blocks tab would remain in my browser. I went back to the code blocks with the back key easily (I was working on one of the 4 screens, this one with 550 blocks).
What I suggest is that the advertiser opens a new tab.
