I can't imagine a feature better suited for Construct than string editing in-app

Simple stuff like selecting a whole row of events and changing the object being referred to in the 'if mouse clicks object' and replacing every string of x with y by searching withing a certain selection.

I can't tell you how often I've ever had to save the game folder and open it up in Notepad++ to change things, or just copy-paste 40-odd events for something that could be far more simple.

Does anyone else have this issue?

Select the events and press r

Though if you have need for this a lot, it sounds a bit like a programming style issue, where instead of having the same events again for multiple objects you could use families or instance variables

Select the events and press r

That's insane. I need to be better at reading the guides. Thank you!
