Here's a few I've done:
--I have TealWheel assigned as the side key, & I have an upward pen stroke assigned to trigger it, so my TealWheel now launches just like the old TealOS wave launcher did.
--I have the 2, 5, & 8 keys assigned as Dig+ to change the screen brightness to 40. 125, & 255, respectively.
--For Blazer, I've got the volume keys assigned as pen taps on the up/down scroll bar arrows, so I get smooth scrolling in 'Optimized Mode' instead of that annoying choppiness (still have no idea why they only made 'Wide Mode smooth scroll

)
--Ive got the space bar set to trigger a quick launch of BatteryDA, since I'm constantly checking it.
--My Pics & Videos is set to go 100% brightness on launch & return to default when exited (I believe that's in the wiki, no?
**I'll be the first to admit that the Hobbyist Software apps are amazing, but I'm obsessed with optimization, & I've managed to completely replace every single feature that I use (pretty much everything) & use up less memory, have less (in fact zero!) effect on speed, & (best of all!) cost absolutely nothing. Here's a couple ways Apt helped:
**I can't live without KeyCaps 600, & Butler's workaround to keep the Favorites keys working is great! But the exact same things can be assigned within Apt, so I can delete all those Favorite buttons from Phone (& make tab navigatuon within TAKEphONE much less annoying, to boot)
**Butler's Volume Keys feature can also be reproduced with Apt, & actually even improved with Blazer to be set as right/left instead, so each link on the page can be scrolled through with the volume keys.
**I also have brightness set to decrease at 2200 & increase at 0700, afeature I used to use with Power Hero.
There's more, but my thumb is getting tired

I'm still very new to the app & I've got a lot of ideas clunking around in my head, so I'm looking forward to learning to write macros & really push this app to it's full potential.
