I know that title smacks of n00b, but I've fallen a little bit behind the times re: 3rd-party add-ons ever since I got myself a 'real job' earlier this year. I used to be one of the biggest proponents of datamining / data analysis tools / EV-calculators and the like, but I just haven't had as much time to keep up with the general populace in that realm, and I think my winrate has probably suffered to some extent as a result. So I'm asking the following: what 3rd-party add-ons (apart from PT/HEM or datamining utilities, which I'm assuming most everyone has) do you think have been most beneficial to your game? I basically have to be far more selective in what tools I choose to learn about in my limited free time, and want to know which ones have become most popular/useful.

Bet pot and its not close.

That's quite constrained.
imo Window Guard and The Opener are very useful

Well I tried to give it some context with the rest of my post. In a nutshell, I have limited time now that I'm a working stiff. I just don't have the time to try out every newfangled 3rd-party add-on like I used to. I'm not averse to putting in the hours required to learn a new app, and what-not. I just need help in focusing my time/energies. What should I go for?

1)bet pot
2)Poker Stove
3)stars planner for Auto Buyin/Rebuy (others will work but i like this one the best)
( Also cool for mass sit out/sit in)

for stars:
betpot AHK
starsplanner AHK
starsassistant AHK

For fulltilt:
FullTilt Shortcuts
FullTilt Planner

For Party
PartryAHKPlanner
PartySNGHelper

You forgot auto reloader. SAss is cool, or _dave_'s beta version of urgent table .

The Opener is the must have, for any site/thing, IMO.

"beneficial to your game" - the advanced generation of EV calculators, StoxEV and/or PokerRazor must be fairly high up on the list.

StoxEV for analysis
Spadeye for table selection
BetPot (ahk script)
Partycashgame tool (ahk script)
Party AHK Planner (ahk script)

he asked for three

Did you see my screen shot of The Opener?? LOL at only picking 3.

Hell, name as many as you want -- i was trying to just keep people focused instead of spitting out a laundry list of anything and everything they have installed on their cpu. My interest, remember, is picking those few that I have time to really immerse myself in.
