any idea where TP Design 4 is?

It's in Software under the MXD/MXT touch panels.

I miss how easy it used to be to find everything.

I appreciate the feedback on the current website design and have shared it with the marketing team who manages it. Additionally, we are reviewing the technical assets available on the website to better meet your needs. Today, we have variation from brand to brand and even product to product at times. As technologists ourselves, we see the disparity and are actively working to improve the way we share information. Keep the feedback coming - just maybe in a dedicated thread.
