I don't mind browsing photos. I will tag the ones I know I'll want to scrap with soon, in LR. Or if they are edited, I will plunk them into a folder on the computer.
I have a lot of phone pics to scrap with and I store those in dropbox, so its easy enough to scroll thru and select which ones to download, which is nice b/c I can do this on any computer, anywhere.
I like the randomness of looking thru photos for a kit b/c often times I will choose a photo that I might not have originally thought of for that theme/idea KWIM?
So, I'm a total "wing it" kind of person
