@ Spearfish,
regarding some options you have:
1. GCB2
I think you refer to the old GCB when talking about seven years of development. GCB2 is another effort which makes good improvements IMO.

You can get V 1.12 there. It has a wonderful GUI, action is fast and furious. V 1.14 will come in a few months I think according to dewitt´s statements. 1.14 will bring a much enhanced database, many improvements and several new scens you might like.
2. Fleet Command
Oldie but goldie so to say. Good, rather modern GUI. Price is only 9.99 USD, the current NWP update 19.01 is for free, giving a much enhanced database and countless improvements. This one is still alive and has a solid community. The main problem seem to be hardware issues with nvidia graphics adapters and Win 7 compatibility issues.

3. Red Pill
Look at the screenshots and the discussions over there. Real pros, on their way creating maybe the ultimate naval warfare sim. I´m sure they´ll make it, those are the guys who brought H2 through the dark times to H3, in close teamwork with H3 coder Jesse Spears. These are the guys who created db2000 and tons of high end scens for it.

4. Enjoy your Harpoon 3 ANW
Focus on HUD 3, edited by Darren Buckley who works with and for AGSI and thus has deep insights in the game engine. Give AGSI feedback regarding the game engine and the HUD3.
If you like the classical H2/H3 interface there is no reason to get confused and leave it. The personal bug test is if you can have good fights with logical AI behaviour - and not non-supported third party lists (you can read about that in Erik´s statement regarding Ultimate Edition).
If you think this is the case - enjoy your time with Harpoon!
Hope that helps.
