I'm not sure if this site is an appropriate place for this kind of "question", but figured it might help to give some newer players some tips (I'm also looking for your tips).
I wish I had known that:
You need not use autopilot to move around. Simply right click on an object in space (or the overview) and click warp to 0.
You can stack your turrets / launchers by dragging and dropping them on top of each other whilst holding shift (either on HUD or fitting window (note: must be of the same type and have no ammo loaded)). This means you dont have to click F1 - F6 to fire off all your guns! One click ftw!
You can open two windows of the same type by holding down shift when you click. Want to look at two toons at once to see if one is an alt? Want to compare the stats of a microwarpdrive and an afterburner? Simply click show info whilst holding down shift. Two windos! Wallah!
You can compare sets of the same type of module by using the compare tool. Show info --> Variations --> Compare.
You can set up variations of your overview and save them! What? Really? Yes. No more veldspar!
Low security space really isn't that dangerous (usually). Nulsec is even safer (mainly). Despite its status, high security space does allow you to be killed... in your new retriever... by a corpmate.
Ombey's maps kick the butt of all things eve.
You are never safe. Not even if you are afk.
I wish I had known that clearing out your bookmarks, contacts and evemail made a substantial difference to the amount of lag you suffer from.
