Meemo alternative/replacement

[cloudron_hacky]

Hi,
I love the simplicity of Meemo and I am using it extensively, but the shortcomings, primarily MD rendering (checkboxes, strike-through), do limit its usage for me.
Looking for an alternative I stumbled un Memos: https://www.usememos.com/
It seems to be very similar in its approach, and it looks as if it does not suffer from the same limitations.
Could it be an alternative or even a replacement?
