Ok, so I took the plunge and threw SenseHero 2.2 on my HERO. As with many others I was curious as to why i should upgrade. Even now im still trying to find new things to do with 2.1 that i couldnt do before. I thought why have a thread that people can post new things about 2.1 ROMs so that fence sitters can have a decision. So put up the apps/widgets etc that are 2.1 only and why they are so great. Also remember to state if it is ROM dependant (Villain/SenseHero etc) I am on SenseHero 2.2 the pinch zoom in home screen that shows an overview of all your 7 screens is wonderful. It makes getting to the end screens so much quicker, and it looks super flashy. At first i didnt like the theme but now i really quite like it. Live Wallpapers & 3D gallery they are pretty nifty, however on my device were not so smooth so I uninstalled as it is really just eye candy and does not add to the use of the phone. Much the same with 3d gallery, i had a few minor problems but was happy with the original gallery so switched back. Your experience with these may differ though so they are worth a look. Bluetooth file transfer is working? Or so i have heard, i havn't tested yet though Google Goggles, Although 1.6 is required, most people are on 1.5 roms. It is a really cool app, works great when wanting an online price as opposed to a store price. Ive used it to find some info on books for uni etc. It stores your history so you can recall everything you have searched. AOSP Keyboard, I got quite used to the HTC keyboard but once i swapper it for this there was no going back. Much quiker than HTC keyboard and a lot easier to type. Though i do miss the long press for symbols, i can live without them. As for apps and widgets, so far im not too sure. I hope some others can suggest some.
