## todo
- [ ] sort the issues list before the list() function
1. the issues with "done" status should be printed absolutely first in order of priority (those with lowest priority first)
2. the issues with "todo" status should be printed last in order of priority
- [ ] add "help" subcommand
- [ ] add "-t" flag to allow the user to filter which tags they want to see
- [ ] add "summary" subcommand to get a list of how many issues of each tag exist
- [ ] one cool thing would be a "tree" subcommand so that the user can see more visually in which files the most issues exist
- [ ] add logic so that if the target file is inside a "target" directory it is ignored
- [x] perhaps add some concatenation to the filename in the list() function in some way, perhaps turn the home folder into just "~"
