While I don't doubt your good intentions, I don't think "interface improvements" is more interesting than "caravans, persistent trade resources and army deployment" to Toady right now (at the risk of appearing as if I can magically read Toady's mind).
I believe Toady works on what is most interesting to him at the moment, and this belief is based on what I have read in his dev notes (far clearer than most other software authors I've seen). No matter what you think is "best for Dwarf Fortress", one thing is certain - Toady will work on what Toady wants.
Oh, absolutely. I agree that he does what most interests him, and thats all fair and good. Having only donated $0.02 USD to this project thus far, I don't presume any personal entitlement. And don't get the wrong idea, I really want to send my army of thirty dwarves on a loot and pillage run to finally end these goblin ambushes.
However I have worked in a mod before, the Project Reality mod of Battlefield 2. They had robust gameplay changes in mind when they started out. Simple things, like changing accuracy levels for weapons and removing kill messages, created a totally new feel for the game. But we still had ridiculous crap left over from the original Battlefield 2. Maps had to be re-balanced for the new casualty rates. Capture points had to be shifted. And mappers like myself didn't want to go back into old product to fix it up, we wanted to make new product we could proudly give to the community with our signatures written in the pavement somewhere. But if we didn't practically draft developers to fix maps, we'd continue with good gameplay hampered by a bad game enviroment for much, much longer.
That's how I feel about an interface. It takes precedence not because its fun or interesting to work on, but because all of this amazing stuff is hidden under an old coat of varnish that makes other gamers, with donation money burning their pockets, walk by and say "So what?". I'm not here to cry and get my way. I don't need a 3D or 2D sprite interface. I just think its in Dwarf Fortress' best interest, even if its not interesting to Toady, to improve the interface through whatever means he prefers. And its my opinion a good way to do that would be through a 3rd party interface.
P.S. Do you see what I did in my post? I wrote an entire post without using the word "you". Its a very polite way to write in
an argument a debate because then you won't put words into people's mouths.
P.S.S. A reader may notice my previous post scriptum utilized the word "you", and thus created the impression I was accusing all other readers of appearing to put words into other's mouths. This action was deliberate in order to drive home a rhetorical point.
P.P.S. Is it Post Post Scriptum or Post Scriptum Something?
