Includes the project ideas and Plans that I have.

  1. I want to create some sort of automatic telegram channel content downloader, meaning if there is something that I want from a channel to be downloaded it should download it automatically.
  2. Fuzzy search enabled notes manager and synchronisations, that will totally be helpful if merged with bookmarks
  • iterfzf for fuzzy finding
  • git for synchronisation
  • xsel or something similar for clipboard
  1. Automatic mount with rclone and having some good speed
  2. An automated script for the automation of scenarios in MPTCP
