So, as I previously hinted, I have taken a quick look atthe open issues and suggestions over at org-bullets. Here's what I found:

• Perfomance Questions 🖥️ 🔥
  It seems that there wereperformance issues related to the rendering of UTF8 characters. This seems to have been primarily an issue on windows, but sadly I currently have no way to test that. I would appreciate checking this package's performance on a modern windows computer!
• TODO-specific header bullets ☑️
  Another interesting suggestion wasto add special bullets forTODO andDONE headings, as suggested by@sumitsahrawat. I would like to know if people are generally interested in such a feature.
• Bug Reports 🦋
  Different codebase, different bugs. Currently I have squashed all bugs I could find, but I have more faith in my ability to produce bugs than in my ability tofind them. If any strange behaviour crops up, be sure to open an issue!

That seems to cover the issue tracker of org-bullets. I would greatly appreciate comments regarding the points I found, how they may be applicable to or desirable for this package.

Thanks to everyone in advance!
