"Quick win" UI adjustments for quality

[veniseberte]

These should be small fixes, and they might seem trivial, but as a UX-UI Designer, I can say they actually make a big difference in making the entire app look polished and high quality.

On the windows desktop app:

1. For some reason, icons and text in a lot of the UI are kind of blurry/fuzzy. At first I noticed this on the icons and assumed the devs used something other than SVG format for those (if they aren't SVG they really should be changed to that, not only is it a good practice but that way the icons normally will never be fuzzy no matter the device and resolution).
   I don't see what would make text blurry though. Here's an example:
   

Although the fuzzyness is minimal, I can tell the difference and it makes the whole UI feel weird. Especially since it's not consistent across the app; in some areas the text is nice and clear.

2. When sending a message in a text channel, there's an inconsistency in the vertical spacing between a message that's attached to the username above it, and the following messages that the same user sends, making it look like the first 2 text lines are closer together than the others :
   
   In the above screenshot we can also notice the username is misaligned with the "Today at 10:32 AM" text.

3. Emoji reactions shown on a text message are misaligned with the number next to it:
   
   (also, personal opinion: the font for the number doesn't need to be in bold, that sticks out a bit too much for secondary information)

Those are the things I've noticed so far, I've only been trying the app for a day :)
