Finally found what makes my script lag a lot on big grids, and I think I fixed that problem today.
Together with that, I improved my script, so it can update itself, without help of timer!

Thanks to my friend th3_smart, I've manged to add pseudo-graphic progress bar, which replaced straight line, directly under overall shield status. Now you cold easily see, how many mPt/kPt/Pt charged on your shield with graphic representation

- Added some foolproof checks, for lcd and shields availability.
- Added small advice, shown if shield unavailable.
- A little adjusted horizontal line between overall and extended info.

Made, and published in workshop...
