I circumvent such problems with UIs and drafting of posts by using a local installation of a markdown editor. Plenty of such editors are available with the benefit that one doesn't have to have an Internet connection when writing. Perfect for some writing in nature or something ;) I have used a local installation of MacDown editor for the last 7 years or so and still continue to use that one. This is for MacBook/Apple. Never tried one for Windows systems, but plenty of them around.
Also, you could consider drafting in PeakD, and copy/paste into 3Speak when preparing the video upload, and when done so, remove the draft from PeakD ;) I know, some of the markdown is different in 3Speak to PeakD, but that can be avoided when getting to know what works and what doesn't work.
I did not know all that was possible -- thank you for the new options!
Let me know when you have questions, I maybe of support somehow.
A screenshot of my MacDown editor, it has this WYSIWYG (What You See Is What You Get) screen. Not 100% correct with how PeakD shows (eg space between title and text is different), but none of the HIVE UIs are showing these types of things exactly the same anyway. After some time working with such an editor and WYSIWYG screen, the differences between this editor and HiveBlog, Ecency, PeakD, Leo are easy to work with.
