DreadNatty08 - Thank you for telling me where the setting is, I had received my Prime, used the stock launcher, Go Launcher (which I was used to from my Atrix) and Apex, so I was having the hardest time remembering where I'd seen that. Do you happen to know if the Amazon App Store or any other common dl sites have that as an option as well? I can see how it would be a dumb toggle to have on to many, but for me it helps keep things organized. I have folders on my homescreen for Games, Communication, Utilities, Music, Browser (from experimenting, who doesn't have more than one?), etc. I like to come 'home' from shopping to find the icons of apps I've picked up so I can drag them into the appropriate folders, or leave them out until they're explored.
Critcher - Hmmm, I wonder if that's what it is indeed! The quirkiness, I mean, obviously DreadNatty08 set me straight as to where the directive to place the icon originated from anyway. Well, thanks for helping me with that too, so it's the screen where the play icon is set that determines the placement of the new app icon.
Ha, well, I laughed at it as well, but if you get behind in cleaning up the screen it will, of course, come to be a true fact - no new app icon on that screen! I always saw it as quirkiness, though I love your idea of laughing at it like a naughty 4 yo! So if it's Apex, I dunno, I may go back to Go Launcher anyway, I love it on my phone, I had folders in my dock and it has wonderful themes & extensions. I seem to recall it had some things lacking in their tablet offering that has since improved (since I see it's updates on my phone). I haven't been able to get used to how with Apex you can't multi select from the app drawer to build a folder or go from the folder to pick apps instead of always being shunted to just one option: go to the app drawer, pick one icon, at a time, get it to the correct desktop, then into a folder of choice. I'd much rather start with a folder of Games & go shopping through my app drawer. I know Apex has had some updates, but I haven't been able to seem to make it work, I guess our gui's don't line up as well as others'.
I don't think I've figured out how to outfit my dock with Apex even! Btw, speaking of games, thanks for the tip on Cogs, I've gotten the free demo & have it's icon sitting on my homescreen, waiting for the chance to get into it!
