Manifold is written by one person. Reports and questions reach me directly, and the useful ones change the program quickly.

Something is wrong

Open an issue on GitHub. What helps most, in order:

• What you did and what happened. "I selected across a formula and the highlight flickered" is enough to start on.
• A screenshot, or a recording. Several of the subtlest faults in this editor were found by counting pixels in a screen recording — if you can show it, it can be measured.
• Which model, if the assistant is involved. Almost every "it is slow" or "it said something wrong" turns out to be about the model rather than the editor, and the app names it for you.
• Your platform, and whether you were running from source.

Something is missing

Also an issue, and say what you were trying to write when you noticed. Features here get built because somebody hit a wall in a real document; that context is what makes the difference between a good guess and the right one.

Anything else

If you are writing in Hebrew and something about the direction, the fonts or the typesetting is wrong, I especially want to hear it — that is the part of this program that has the least company and the most to get right.
