@Alexey: I'll try to write and post an in-depth review this weekend at https://www.macupdate.com/app/mac/55256/cudatext as you suggested. If you know of any other sites where posting a review, now or in future, would be helpful just tell me. Cud really needs more exposure
BTW, yesterday I added the cuda_spell_checker plugin for Windows and Linux... impressive. Well done! I like the feature that even in source code some parts of the text can be checked (never seen this in an editor before ) though I do have a problem with my private markdown lexer (I am investigating and may report).
