You'll get a ton of people who all have different opinions on what to use to do what.
If you want an all in one, have a ton of Graphics memory, and don't mind using it, El Tank will do all that you ask.
If you want to cut down on graphics issues due to a lower memory card, Find It! replaces Bandit Sight very well, IMO. Alinco does to a lesser extent, but not (yet) as customizable with armor/weapon stats. Find It! also will salvage, although you have to set the rules for it, but that's not hard. I believe Alinco does this via Decal Hotkey System as well.
Go Arrow will do route finding, shows maps in game, shows an arrow to point you in the directions of coords you enter, etc.
You can now map a key in game, (go to keyboard config) to "Open Next Unopened Corpse", which is just the best thing since sliced bread for me, lol.
AgentZ does a lot of great things as well, from xp tracking, level information, chat filters (filter 0 damage hits, melee evades, etc) and can do most custom aliases.
And there are many other new plug-ins out there that do other things, check Suca's Site (link is in the first post on this forum) and look for the ones that say they are "Decal 7 Compatable".
