Spoiler: In game examplesI wasn't satisfied with the default cursors that GZDoom uses in a way that they don't really conform to the typical UI standards of looking "pointy", for lack of a better explanation. I made these in a way that they'd blend into the base games, but yet still do a good job of looking "UI-ey".
The designs I chose were meant to fit the theme of the base games: sci-fi for Doom and Strife; for Heretic and Hexen, the gloves are a nod to Warcraft and Diablo (Heretic = Corvus' leather gloves, Hexen = Fighter's gauntlet); while the spork is... well, Chex Quest is related to food, so...
Instructions: with nash_cursor.pk3 loaded, go to Mouse Options and set the "cursor" to "default". This will make sure the cursor changes according to the base game you're playing.
