I could use some #FediHelp .

As my long-running readers are probably aware, I schedule a _lot_ of posts in advance. I use @bufferapp for this, and I am largely satisfied with this, except for one thing:

They have a fixed character limit of 500 for posts, and thus I cannot make use of the full 10,000 characters of my instance.

This is bad, since most of my scheduled posts are German folk tales exceeding this character limit, and thus I am forced to use screenshots instead of plain texts - which is terrible from an #accessibility point of view (yes, there are readers that can identify the text, but I'd rather use plain text in the first place). So I am looking for alternatives. Here are my requirements:

- It must have a web interface I can use on my desktop PC - I grew up with proper screens and keyboards, and while I _can_ use a smart phone or tablet for complex stuff, I do not find the experience enjoyable.
- It must have a calendar view instead of being a simple, scrollable list - I often schedule posts weeks in advance, and I want to be able to keep track of what is scheduled.
- It must make full use of the character limits of each instance.
- It must allow for scheduling threads - quite a few of the tales I am posting exceed the 10,000 character limit.
- It must work with #Mastodon . While I am aware that other #Fediverse systems (such as #Friendica ) have scheduling options of their own, switching to an entirely different system is a drastic step that I only want to explore when all other options have been exhausted.

Does anyone have any suggestions?
