OKAY! Found my solution: an app called ScreenModeWidget
It's a little widget that toggles between three modes:
Sleep Auto: Normal screen action, only power/lock button locks/unlocks phone, still slide
Awake Stay: Power/lock button, camera button, or volume buttons wake and unlock the screen, no need to slide (sliding is unnecessary IMO, never hit the button accidentally). Also great because if you just slide the keyboard out it's already unlocked!
Screen Stay: Screen never locks, just stays awake unless you lock it with the lock button
I LOVE this app, it's so amazing, whenever I have the phone sitting on my desk and get a text, just tap the camera button (not even all the way, just the half-way depression), and there's my screen ready to go. I also really like being able to slide open the keyboard and just start doing stuff, the sliding seems like an unnecessary step to me. Anyways, hope this helps anyone frustrated with having to hit the power button and then slide the lock screen!
