@LittleWytch Welcome to Qoto, it's nice to read your impressions, specially coming from someone who has looked at other instances and perceives the differences. 😃
The large post size limit is indeed nice, and something I value and had campaigned for. Alas, many admins are Twitter veterans, used to the terse (and many times opaque) short posts and don't see a need for more.
The lead developer of Mastodon included, unfortunately - he refuses to make it easier to keep a customized larger size for maximum characters limit, burying it in various lines in different files in the source code -- making it laborious for admins every time a new update come around.
@design_RG because code gives me a headache, there is a lot about it that I don't understand. Maybe someday it can be forked and this version can become the new standard. ❤️
