Thanks for the list, thadoggfather. I just installed SwipeShiftCaret from your recommendation, and it is excellent. Your testament also convinced me that AdBlocker is worth purchasing. I had not heard of Respringcachefix before, but Ive added it too.
Here is my full list. I have made bold the tweaks I think youll be interested in:
3GUnrestrictor5 Use wifi-only features on 3G
Accelerate Faster (or slower) animations, as you see fit
Activator Activator!
AdBlocker AdBlocker!
aDownloader I dont use this anymore.
AntiTint Makes the iOS 6 status bar always black, rather than changing colors.
AppCent Shows percent progress for app downloads
AppStoreUpdateSize Shows size of updates in the App Store
AskToCall Pops up a dialog asking if you are sure you want to call. I use this because I find it really annoying that tapping on an item in Recent Calls by default immediately calls back, rather than viewing the contact info.
BrightnessIcons Homescreen icons to increase and decrease brightness.
BytaFont I have never used this, but I occasionally contemplate it. I might try FreeSans one day.
Cyntact Shows pictures in Contacts list
DebianSaverLaunchDaemon Whenever you install a Cydia package, this utility automatically copies the .deb file to the /var/mobile/Documents/DebianSaver directory. That way you can easily backup your Cydia packages, and also have the ability to manually downgrade them (by installing a previous version from its .deb).
DeleteWord Hold the Shift key and tap Delete to erase the previous whole word. Theres a better version called DeleteWorld, but its not iOS 6 compatible yet.
DietBar Makes Navigation bars thinner
DietBulletin Makes notification banners thinner (so they fit in the Status Bar)
Dimmer Lets you make your screen even darker
DisableNCSwitch Prevents the Notification Center from swiping down in Fullscreen apps
DismissMyKeyboard Swiping from Spacebar to Enter key makes the keyboard go away. Perfect for Messages where typing a long message normally makes it impossible to scroll up and see the earlier conversation while typing, but useful anywhere.
FastCopy This doesnt work on iOS 6 yet, but it is supposed to eliminate the delay before the Copy action menu pops up. It worked in iOS 5, and I have it installed because it doesnt hurt, and that way Ill know as soon as it gets updated.
f.lux Warm display temperature at night
FolderEnhancer I think this is better than InfiniFolders, but your preferences may be different.
FullScreenSafari Swipe actions are great, though some of them dont work quite right on iOS 6. Notably, I cant get the 2-finger swipe Up and Down to trigger the Scroll to Top and Scroll to Bottom actions.
IconRenamer Lets you rename icons on the Springboard
iFile File browser
KillBackground Lets you close all apps at once from the switcher in wiggle mode.
LastApp Lets you set an Activator action to return to the most recent other app. Good for switching back and forth.
MobileTerminal Terminal
Monocle Lets you set an Activator action to put an app into fullscreen mode. I set it to only hide the Status Bar, leaving the navigation and tab bars alone.
MultiIconMover Select multiple app/folder icons and move them all at once
Nitrous Much faster (4× in my tests) Javascript in every webview outside Safari, including other browsers
NoSpot Eliminates the Spotlight page
RespringCacheFix Clean up junk files
RotationInhibitor Lets you set an Activator action to lock the screen orientation.
SafariBookmarks Moves the Reading List and History lines out of the Bookmarks list.
SafariDownloadEnabler Download things from Safari. One shortcoming is I dont see a way to download the webpage that is currently open, only ways to download pages that are linked to (by holding down on the link).
SafariPDFPrinter Lets you print a webpage to PDF
SBSettings I like it better than NCSettings because you can have 12 toggles visible at once.
ShowCase Makes the keyboard show lowercase letters when appropriate. Even works for Greek and other languages.
SpringFlash Lets you set an Activator action to turn on the torch. I set it to Lock Button Short Hold, so I have a physical flashlight switch.
SwipeShiftCaret Awesome text insertion point and selection manipulation
TabPlus Lets you open unlimited tabs in Safari
TetherMe Enables native tethering, uses phone apn
TopographyForGoogleMaps Lets you set Google Maps to topo view
UniversalVideoDownloader Lets you download videos from any app.
WebScrollian Much faster scrolling in web views
WifiPasswords View your saved Wifi networks and passwords. Great for times when someone asks you for a Wifi password.
WinterBoard I only have one theme, which is a custom lockscreen I made that shows the current phase of the moon.
xMessages Lets you make Messages show timestamps for all messages. Has some other contact-picture features, but they mostly broke in iOS 6. So I would actually recommend SMSTimestamps if you just want the timestamp for every message.
I am still waiting on IconRotator and appslide to be updated for iOS 6.
