Problems using "Kblocks" package for drawing "Block diagrams"

Question

My first question is:
How to move or shift the label on a given link like in the attached photo?
My second question is:
How to bend the link to become a 90 deg as shown in the picture?
I attached my code in tex.

usepackage{kblocks}

The kblocks pacakge has been updated. However, it might take a while for the code changes to reflect on the package arvhive. You can, however, download it from
https://github.com/somefunAgba/kblocks
Here is probably the diagram that you want to realize
begin{kblock}
% ref
kJumpCS{spt}
% top blocks
kMarkNodeRight{0cm}{0cm}{$I^star$}{spt}{inI}
kPlusMinusDown{inI}{sb1}{1.cm}
kTFRight[0.2cm]{sb1}{tfb1}{$s$}
kTFBelow[0.5cm]{sb1}{tfb2}{$frac{1}{2}$}  
kPlusDownPlusUpL{tfb2}{sb2}{0cm}
kMinusPlusUp{tfb1}{sb3}{0cm}
kTFRight[0cm]{sb3}{tfb3}{$0.2$}

kMarkNodeAbove{0cm}{0cm}{$V_{dc}$}{inI}{inVdc}
