First of all, I’d like to clarify one thing about this project, as it will answer many "why" questions.
Originally, I just wanted to build a Linux version to see if it would work - nothing more. If I had bigger plans, I would have done things very differently. But now, it is what it is, and many things are implemented in a less-than-optimal way (and mostly not by me, but by the original creator and those who worked on the port my version is based on).
Some things are easy to improve - I simply missed them (and no one reported them). Others, however, would be unreasonable to "fix" at this stage, as doing so could cause more harm than good and would take too much time.
