To set SaidIt to load fresh comments, one must merely modify the source code to be able to do so, most likely by merging the very new commit from several days ago (or maybe a couple weeks ago?) that allowed RedReader to do the same, and probably all the other commits too, hopefully then merging all those merges into the main repository for the SaidIt app so that others can take advantage of them as well. The current SaidIt app is forked from a very old version of RedReader, so doesn't include that feature yet or even a lot of the features much older than it, like the automatic muting of videos played. I plan to merge many of the changes myself at some point, if no one else gets to them first.

The current feature to reload everything by default actually annoys me a lot, as it makes loading comments take a couple seconds instead of loading them near-instantly, and also automatically tries to load a non-working version when Reddit is down instead of using the cached version. I wish there was a way to disable it or make it a bit more sane, but unfortunately, no such option exists yet.
