As a follow-up to my lemmings history post, this post will keep track of three separate level pack lists: packs I have beaten (green), packs I'm currently playing through (blue), and packs I haven't played yet (red). The number in parenthesis after the name of each list indicates the total number of packs I have listed. For the lists, I'm simply going through Wafflem's stickied list of level packs he made on the list of levels in the Neolemmix board. Obviously there's way more packs out there than just the ones on his list, but if I list every single one I'll never be done. I'm only going to be making lists for Lemmini, Superlemmini, Dos, and Neolemmix, as I have no intention to play any packs on any other platform. For each engine, the number in parenthesis after the name of the engine indicates the number of packs I have listed for the engine. Each engine first lists the author followed by the name of the pack. The number in parenthesis after the author's name indicates the number of packs by the author I have listed, not necessarily the total number of packs the author has released. The number of packs for each engine for each of the three lists is then added to get a total number for each list. Keeping lists is a personal thing of mine that I like to do, and I think this is also me, but I like seeing things crossed out on a list as they're completed. Given there's so many level packs, I think these lists are a great way for me to personally see how much overall progress I have made, as well as a great way for record bookkeeping and to keep organized. For packs I'm currently playing and eventually beat, I'll either strike them out or move them to the completed list. I haven't decided what I'll do with that yet.
edit: For now, for in-progress packs I complete, I'm going to do both a strikethrough of the level pack name in the in-progress list and move the beaten pack to the "completed" list.
Level Packs I Have 100% Completed (122)
Dos (5)
Mazu (1) - Mazulems
ssam1221 (3) - KillerMaster's ver. 1, KillerMaster's ver. 2, and ssam1221's Lemmings (although I recall one of the levels in I think ver. 2 freezing completely during play and so I haven't completed it, perhaps due to hidden steel around the marble exits
namida (1) - Lemmings Plus Dos (mostly completed, 148/150, only two levels I haven't solved, one of which was replaced by a different level in later versions because it was way too difficult to execute. I know the solutions to the two levels, just couldn't bother to execute them)

Dodochacalo (4) - Dovelems, Cachapack, Dodopack, and Franlems
Pieuw (1) - Pimolems

Essman (1) - Copycat (came back to this pack 11/13/20 to play it again so that I have my own set of replays which I didn't have the last time I played months ago due to not having the setting to automatically save successful replays enabled [complete replay set 11/14/20])

Pack loads fine in 10.13.18, but two levels crash due to complaining that it can't load kiwi.dat, which probably means the tileset wasn't updated to the latest Old Formats NL version; started 12/20/20, completed 12/21/20, added to "completed" list 12/21/20)

I'll probably eventually play the other packs not on Wafflem's list that are on the level boards that I didn't list, but the ones listed here are the ones that I'm certain that I will play.
Also, suggestions are welcome for how I could maybe make the lists better looking. I initially did the level packs in spoilers, with only the name of the engine visible, but I later discarded that, as I really want everyone here to be able to see the level pack names without them being hidden in spoiler tags. Especially with how I have plenty of engines listed it's annoying to click through all of them to reveal the level packs I have listed under each one. This is the best I've managed to come up with for the time being.
