I changed enemies to 512 because people were running out of custom enemy slots and I remember I made a joke about combo aliases once -- something about trees. I imagine it was hilarious. :)
[edit] (I also misread this thread.)
..Do people actually use all of them?* Increased the maximum usable combo aliases to 2048. Pro Tip: Don't use them all for trees!
* Added Import and Export Combo Aliases functionality in the File->Import/Export Menu. ( Gleeok, 2012-06-11 01:06:28 )
