For longer-going games, roll20 logs can get quite large - a fellow player attempted to retrieve the logs and from what we can tell there's 52 MB of raw text. Just loading up any older, even longer games, we can't even get an estimate. Trying to load the page normally is practically impossible, often-times crashing browsers even on absolute powerhouses of PCs. It's pretty obvious there's a problem to the logs as a whole, but at the very least, there could be an option to just go to content in the drop-down menu, click on "Chat archives" and get an option saying "Download raw logs as .txt file" alongside viewing it in-browser. What would be provided is a text file of literally any public chat in the archives. It'd definitely be a great start and allow for many players to get logs for games long-since passed.
