If it’s broken, please post a bug report with detailed steps would help us fix it. And also many people are using it without any issues, myself included, so it could be something wrong on your end (how you set it up).
And no offense, posting a feature request for an existing feature without mentioning you’ve tried it is not exactly helpful.
WorkFlowy features do not match to Dynalist one-to-one, and I’m not even sure what do you mean by “preset”. Do you mean a text file that stores your configurations? Or just “magically” import all your settings from WorkFlowy? I’m sorry but they have to expose it somehow for us to access it.
I don’t know how many shortcuts you’d like to set up, but with the amount of frequently used shortcuts WorkFlowy has, it won’t take more than a few minutes. That doesn’t warrant spending our development time on it, in my opinion.
