So you'd rather play with mods that don't have their music and sound effects implemented?- Mod sound & music playback reimplementation & fixes.
You'd rather have mods release on their current structure only to have to update again later when they optimize/redesign their world generation layers and such?- Object-oriented topological sorting-based redesign of interface layers and world generation passes.
Memory optimizations, especially on a 32-bit app does mean things, because the lighter certain things are, the more mods one can run before running into Out of Memory errors... A huge problem with the current 32-bit only TModloader for 1.3.x- Conversion of Tile to 'struct' for the sake of memory optimizations.
I give you this one, its a nice to have. We do have the in-game mod browser, but I'm certain the TModLoader team would rather shift mod hosting over to Steam so they don't need to continue operating the mod repository they've got currently that powers their in-game mod browser/downloader/installer. I'm sure the TModloader team doesn't get paid to host the mods on the mod browser as it is...- Steam Workshop support - though this may release after TML 1.4, the timing is still a bit undedecided
Out of the four items above, feels to me only one of them aren't more necessary than the others. Steam Workshop Support ... But again, that's up to the team to decide.
