Thanks!
I found the other mod (using Google site search, instead of forum search):
viewtopic.php?f=9&t=7530The mod creator canceled it because it was already done in the default furnace, just not yet merged to the main game:
https://github.com/minetest/minetest_game/pull/200But, I don't know. The patch was over a year ago (and conflicts some new code, I think). I don't really know the current progress on it.
Anyway, I made another
pull request to patch the default furnace using my changes in minetest_game.
You can use (and test) this too by downloading my patched minetest_game (don't enable furnace_time here):
