Recommendation Pls: Looking for a very simple booster mod

[MartinSGill]

Hi

I'm looking for a very simple booster mod that removes my single biggest problem with ships in X4. I've seen lots of complaints about this mechanic but for some reason I'm really struggling to find a mechanic to actually "fix" it.

What I looking for is a mod that does the following:

The booster/afterburner no longer uses the shield capacitor. Ideally it would have it's own capacitor, maybe charged from energy cells.
Ideally it would have a UI, but I can live without that.
It should not be part of a larger "overhaul" mod. This is the only thing I want to change.

Thanks in advance.
