the installed app picker is now connected with the physical tft display so when an app is selected, its windows icon can be used on that specific adeck key and the icon data is now going through the web app, python backend and arduino firmware instead of being only part of the web side so the actual logo can be rendered on the display

• added the icon data flow from the selected app config to the backend and then to the arduino, converted the windows icons into a tft compatible format and added the firmware side code to receive and draw the icon on the correct key

• tested the icon rendering with different installed apps and checked that each icon stays with its selected key while normal commands like git and npm still use the normal command flow

still need to polish the app part so the logos look better and text below them fits properly and the box colors and backgrounds look cleaner on the display
