My foremost interest is for text editing exactly.
My usual setup, Kingsoft Office 5.12.

The use of the device to somehow display a full LibreOffice environment is promising.

(Markdown: well, I want paragraph margins, full text justification and multi-font while I am editing.)

You never use a mouse for formatting. You [SHIFT]+[arrows] and use other shortcuts to apply paragraph styles, or [CTRL]+[B|I|U...] for exceptional styling.

Do you think that this could be improved using a writing app specifically designed for e-ink devices? Is the problem due to the fact that apps on Google Play store are not optimized for e-ink?
Do you know of any text-editor or markdown editor optimized for these devices?

Are you sure you have not simply hit the EPD limit? If the lag is around 150ms, you cannot have better with current e-ink displays.
If the delay is more and chars appear in burst, you should impose a wake-lock, as noted in the past.

It is about time we get an open source rich text editor on Android.
