Devlog 9: New features and a bit of an ui overhaul

So I decided to make the ui a bit more pretty and a few new features
So this is what i added:

• a new cleaner ui
• contact profile picture support
• message time stamping in the ui
• dark theme and theme switcher with persistence

these are just like qol improvements that i decided to add into the app nothing special but like i missed a few features like the dark theme myself so nothing major but i hope these changes makes the app more usable to ppl
