I recently purchased a Pico Omnibus (Dual Expander) and a Pico Unicorn Pack to test out the new Raspberry Pi Pico.
Using the Pimoroni Micropython UF2 gave an easy way to get the demo.py working as an initial step.
Still on the learning curve - and wanting to use other library modules that support different devices from other vendors - is there a way of extracting the Picounicorn Module such that it may be simply copied to the /RP2 folder with other source and library files as part of a larger project, or could a set of modules be made available to allow a pick-and-mix approach.
Given the simplicity of using Micropython and Thonny to learn programming skills, I am sure that there are many new users (like me) that lack the expertise and experience to be able to make the step-change required if one has to also use the C/C++ SDK etc. to make progress to the next level.
