A hierarchy view might be better than the current Z Order bar regarding this.
As it would also allow to create hierarchy relationship directly by drag and dropping objects under/on top of each other in this dedicated view. On top of a lot of new QOL stuff it would allow, such as a way to efficently find and select instances of the current Layout
I filled a detailed request a few weeks ago, Hierarchy View :
construct3-21h2.ideas.aha.io/ideas/C321H2-I-311
If anyone is interested please consider voting for it.
(Also, I made this list of other important QOL/features that could be nice to have in the engine, how they could work in combination with each other, or with already existing features and so on. Some of them are related to Hierarchies/Templates : construct3-21h2.ideas.aha.io/ideas/C321H2-I-318)[/i]
