3000 % FasterFile Saving With Time Travel (lgm2025)

A developer talk about coming up with a new file format for [Drawpile](https://drawpile.net/) with the focus being on the findings and ideas that would be useful for other programs as well. Some of those ideas are already implemented and have brought a massive speedup in file saving and loading, some wilder ideas like continuous autosave with history-altering time-travel are in various states of currently still being worked on, but sufficiently cool to talk about anyway. ## Links * [Drawpile](https://drawpile.net/) Licensed to the public under https://creativecommons.org/licenses/by/4.0/ about this event: https://pretalx.c3voc.de/lgm25-upstream-2025/talk/2882617605/
