In E1 projects exported by the beta version of the Editor, ids are very large strings, like “67d8a3b0-c2b0-4038-8829-4d48c4a4acb9”. Why? (This blows up the preset size, and seems unnecessary.)
(long time programmer guess)
When there’s a need for unique IDs for anything, there’s a lot of code on the net that generates GUIDs (global unique IDs). I first ran across them when working in a Microsoft Windows environment. Saves the programmer the hassle of keeping track of each ID they create and assign themselves.
