Hi bussi,
Seen from the production of the PCB, I have no more issues I stumble upon.
Maybe except some of the TO220 cases are a bit hard to attach to a heat sink, if needed.
When I said you could move U1 to the signal side, you chose a smart, easy and sufficient solution.
But by not moving U1 physically to the "other side" and laying it down to use the PCB ground plane as a heat sink (you have to find a horizontal TO220 footprint, or define one yourself), then you maybe lost the opportunity to put the remaining TO220 cases in-line for easy mount on a common heat sink.
----------------
For your info:
The "vias" you used are quite big. You know you from within pcbnew (the layout program) you can click the "Open Module Editor" button.
Here you define the footprints, and it is perfectly legal to define a 70 mill pad as a component you can use to "stitch" the ground planes.
On the diagram, imagine you want to connect two pins, but the pins are far apart, and you have to "cross" the body of some diagram symbols to do the connection.
Instead of drawing the long connecting line. you can just "extend" the pin line, and place a label on the extension.
Click the "Place the net name" button ( the button with an "A" and a green line under the "A".
All the pin "extensions" (or other connecting lines) where you put a label close above the line, are then connected, and you avoid the diagram looks like a "ratnest" in the layout program, no offense intended.
