R C-R , if I understand you correctly, the preference setting that's similar to auto select layer in Photoshop yes?
Yes,thank you I have found it , A very handy feature in both programs, though I've also found it has it's limits in Ps and tends to get snagged on adjustment layers or layers where I've added some subtle brushstrokes on a layer somewhere above the layer I'm after. I always make a point of naming layers of course but still, when there's a high stack of them, a good sized thumbnail helps.
I'm very new to Infinity Photo and enjoying it immensely but since I am so new to it I can't really comment as yet on how well the "Show Selection in Layers Panel," feature works as a way of selecting layers. I'll no doubt discover how well it works for me as I test it out on multi layer files.
I guess I've just become very accustomed to glancing across at a nice big thumbnail in the Ps layers panel and being able to see what's what.
