Do not sacrifice speed for features.
I enjoy upgrades and new features. However, I also use mighty text to do things fast. I do not enjoy the new loading screen that slows down the initial load time.
Also - now after some update that you did switching between messages is not lightning fast anymore. I have to wait for it to load and spin a little bit.
Give us the option to have just a plain vanilla experience please where super fast load times of everything is the number 1 priority. I don't care about color, I care that when I switch to another persons message it takes 2 seconds before I can type to them!
