Pain points in existing Twitter writing tools

Hi IndieHackers,

A couple of day ago, I've started by Build in Public project of creating (yet) another Twitter writing tool. If you're interested, you can find more details about the reasoning in my Twitter post below.

For now, I would love to hear your opinion on the current state of Twitter writing tools from those of you who have been using them for a while:
• Are there any pain points when using these tools?
• Is there something that you feel is missing from them?
• What would you change in terms of design to make simpler & more efficient to use?

I'd love to hear your feedback!
