The aim of this page is to give the community the possibility to publish improved layouts of MBHP modules. The original layouts by TK are mostly quick solutions with focus on “first-time-right”, and therefore not very well optimized with regard to area size or number of bridges.
Even small modifications on the original layouts lead to a long process: new etch masks have to be created, the new PCB needs to be tested before it's produced in larger quantities and last but not least the documentation has to be changed: sometimes new photos are required, existing schematics and connection diagrams need to be updated in a way which avoids confusion between different layout revisions, and the support effort in the forum increases, since different layouts have to be taken into account when helping on troubleshooting.
However, all these “issues” should not prevent you from sharing your improvements with the community. They could be part of the next official layout revision. Note that the update cycle is ca. 1-2 years, so it's enough time to think about the best solutions!
When publishing your layouts here, please consider the following:

Suggestion from Rowan: I've got an idea for a small modification to the layout of the DIN and DOUT boards which could cut down wiring in some situations.
What I sugget is to change the spacing BETWEEN J3 -J6 of the DIN and DOUT (I guess this would be useful on the AIN too) to a multiple of 0.1“.
The reason I suggest this is it would allow the DIN/DOUT/AIN to be used as “Plug-in” Modules/daughter boards for strip/matrix board that have DIL Sockets mounted on them. I could mount all my buttons, pots, encoders etc on Strip board, then mount some DIL sockets spaced the same distance apart as J3 - J6 on the other side of the board and plug the module directly on to the board which has the controls on it.
