"Eheh, I can imagine the accidents if you release the grenade by error while dragging it."
it would snap back to its original position, as in the inventory window.
with that joke out of the way, back to business:
no, it was not about getting my hud integrated in mainline (huh, i was going somewhat against mainline policies as far as i understand), it was about getting criticism to direct further development (like prioritizing).
the feedback from before the hud was completed (mostly MCR, and some devs) was often useful (except the purely motivational feedback, but i cannot blame people who don't know me), but when it was completed and the feedback would have been most precise and useful there was total silence.
i did get mouse wheel support included more than it used to be in mainline huds, and that was the original point, so it was success in that way.
but developing this particular hud turned out to be a feedback failure.
some questions could be (hidden in the previous post in a less obvious way):
do you get benefits from contributing to ufo:ai in other fields in rl?
do you get useful feedback even if what you do is crap?
like i tried a campaign in wesnoth, and got constructive negative feedback, the result of which was improvement of the campaign, and also a considerable increase in my writing skills which was useful in real life.
