Enhance Markers Panel

[TeeKayCC]

The markers panel is missing a lot of useful functions. It could allow you to:

- delete markers
- change the color of a marker
- change the type of a marker

(without having to double-click)

The markers panel really needs some work. I just also created a request just like @TaranVH mentioned that the name column needs to be more accessible since it's "the main thing of a marker".

I really hope that this get's some love sometime.

@Kevin-Monahan Do you have any input about this? Maybe a status how this could be improved?
