Couple features that may not be quick, but would be awesome... (and maybe if I get some time in the next couple months I might consider committing them myself)
- First off, add the new ships from PP, so that we can play around with them

- Add ability to define power levels like on the ship (priority levels per module)
- Add ability to simulate with hardpoints deployed or retracted, to see what would be disabled with the set priorities.
As a result of the above you could tweak an overdriven ship config that can still work (I do it regularly where my ship runs at over 100% when deployed, but I run my priority levels carefully configured to be fully functional depending on situation).
Just a thought
Another suggestion would be some means to compare combat capabilities (saw that's been suggested already). Perhaps do some pretty general stuff around raw DPS of all equipped modules. Not true, but gives an idea of overall burst capability. Hell if you added the ability to assign fire groups to weapons as well, you could take the peak DPS of any one fire group.
That aside, I realize that complicates the UI plenty, so not expecting those to be easy features

just throwing them out there.
Either way... AWESOME app... I absolutely LOVE this thing...
