There were so many errors like the animation was getting stuck , the reboot feature not working inside the terminal it just stays stuck , booting animation was getting stuck because of some mismatch between the codes in the files , the layout of the custom timer in pomodoro app was not right i corrected it and then there was problem in the paint app it was not allowing any other color to be used then there was problem with the confirm window buttons for singularity effect it was not working/clickable. somehow i managed to solve them and make them work and finally my project is done after so many typo fixes , debugs and code lines missing.
