You are right. Unfortunately many of us are too private to write reviews. So it takes significant effort sometimes to create burner accounts just for reviews when we are always busy. 

However, since you are the creator of this application which has become a part of my daily life. Here is a direct written review from me to you. 

You have done amazing work. This is a superb application which is well crafted while preserving my privacy and security.

It deserves to be ported become a native Linux application available on flathub.org for maximum adoptability potential. You would see a significant influx of users and contributors to code. As well as continual  financial funding. 

Only negative thing I have to say is that the application will boot me out of replying to someone. This happens whenever I take too long, because the app prioritizes loading new content. This has infuriated me beyond belief dozens of times. I don't know if it is a bug, or a setting that needs to be adjusted. Either way wtf lol. 

To summarize my written review of your application. It deserves a 9/10 positive rating. You and your team are doing an incredible job. I'm proud of you all. Keep up the great work.
