I've been running this a few days now. Very happy I paid for the pro version. I've got a 5 homescreens to play with on my phone and I dedicated one for UltimateFaves because of the space it saves and so the carousel doesn't sit on top of other icons or folders. Actually, the space it takes up is the middle 2 rows of icons so I could add other widgets to the entire top row or bottom row
Real estate for one icon and it gives me access to all of my apps in subgroups. Here's the folders and the apps I put in each for examples:
Systools - root explorer, terminal emulator, wireless tether, quick uninstaller, metamorph, pulldown editor, android vnc, volume control, phone portal, astro, swiFTP
Maps - mapDroyd, google sky map, maps, my maps editor, earth, good food, urbanspoon, nyc bus and subway maps, earthquake, hi-hiker pro,
Music - solo lite, rockout, gstrings, theral dialpad, g-tar free
Media - pandora, music, btunes, gallery, meridian, youtube,media gallery, shazam, droidLive, aldiko
Games- throttle copter, wave blaster, tiny little western. raging thunder, snesoid, nesoid, toss it, robo defense, 2 player reactor, trap
Contacts - I've got hundreds of contacts. In this carousel I've got frequently used favorites. Easy to sms, email, or call on the phone.
Running Tasks - lets you launch, kill, or uninstall the task
running propcesses - lets you kill the process
Settings - lets you toggle airplane mode, rnger settings, gps, bluetooth, network, wifi
Recent tasks - displays up to 16 recent tasks compared to the 6 you get when you longpress the home button.
Basically, any icon I had in a folder I added to this app and then tossed in some that I already had widgets for too, like YouTube and Pandora.
The only 2 features I'd like to see present, and I'll send an email to the developer requesting those would be:
1) When selecting apps to put into the carousels it would be nice if you could filter the list of available apps. Right now I don't know what order the apps are displayed in but with a lot of apps it is hard to find the ones you want. It would be nice to have them alphabetically listed. Other filtering options might be first-last added or size of app or something but I'd be happy having them just listed alphabetically as they are in my app drawer.
2) Let me change the name of the launching icon and let me create an icon for each carousel. Rather than having the above 8-10 carousels all available through a single icon that launches the app and lets me scroll through them all let me have 8-10 icons on my desktop, each one with the option of launching its own collection of carousels. This way one icon might open just "games" and another one just "maps" so I go directly there. It also would give me the option of clicking the "tools" icon and maybe I had 3 carousels in there "food, maps, systools"
Overall, as I stated at the start of this, 5 stars, good useful app.
