  Generally, we categorize issues in the following way, which is largely derived from our old internal work tracking system:
  * ["Bugs"](https://github.com/microsoft/terminal/issues?q=is%3Aopen+is%3Aissue+label%3A%22Issue-Bug%22+) are parts of the Terminal & Console that are not quite working the right way. There's code to already support some scenario, but it's not quite working right. Fixing these is generally a matter of debugging the broken functionality and fixing the wrong code.
