@cgrunenberg – didn’t see this, sorry, and not sure if you were asking me or the OP. But FWIW: having only recently started with DT, I have settled on RTF for notes.
I have meanwhile come up with a solution that’s giving me what I need, for now (Task Lists W/ Checkboxes - #32 by dayknito), but certainly would love and would prefer to have real numbered list checkboxes in RTF! I realize of course this may be low on development priorities.
