Don't be too upset by my pDownloader recommendation, if you don't like it you don't have to install it. Even if you install it, you don't have to use the 'downloader' function. I like having albums in entirety, one song doesn't do it for me. If I want to research, I screen grab it for later. I just find this particular app most effective for ad removal, and unlimited skips.
Added some new tweaks as per recommendations here and elsewhere and would like to make something more clear that was brought up before:
DietBar and DietBulletin are not synonymous.
DietBulletin is notifications slimmed down to the size of status bar, if the message is long it scrolls like a horizontal ticker. Cool.
DietBar slims down unneeded space used vertically on certain UI bars like the top bar of Messages and Music where you can go back or edit (or in the case of Music, flip the 'album art' over to see the tracklist of the album).
Both are excellent, btw. RPetrich man, what a boss.... a BigBoss

His repo is:
rpetri.ch/repo (clever right?)
SMSTimestamps -- wowzah. Good to have as I always get confused over how much time has elapsed. I set it to start noting when theres more than a minute elapsing. But maybe I'll switch it to 5 or more, either way GREAT and worth having.
oOoOo and some nice activator moves I added:
Triple click home button anywhere to activative SpringFlash, springboard integrated Flashlight (separate download in Cydia)
And hold volume up to next track, hold volume down to previous track (only in lock screen, will be great while driving)
And
VolBright is excellent also! Hit volume up and down at same time to change the adjuster to brightness instead of volume. Press both buttons at same time to change it back.
Also, quicker temporarily fix for the 6.1 brightness respring issue than adjusting NCSettings brightness sometimes, until 'BrightnessFix' app supposedly comes along and clears up the firmware-related bug. Good to have anyways as I find myself adjusting brightness more than volume (not including when listening to things, obviously).
Barrel is also now updated to be compatible and works great as far as I can tell with no graphical issues this go round.
DismissMyKeyboard is a gem. Swipe space bar to enter key to dismiss the keyboard in a pinch.
Couldn't believe my list has been topped but it has!
No LS bars sounds intriguing (as does Color'd bars), but again (or maybe I didn't mention it here specifically but elsewhere): I'm not a big Winterboard fan. Got rubbed the wrong way in 1st gen/3G days. Plus modding looks ugly to me when 100% of the apps aren't integrated and I don't have the time or will or even expertise to make that happen.
AppCent is nice too - shows percentage of app download and install on home screen.
