Thoughts I have after taking a look:

• Let's come up with a better configuration API. browser.configureDTL isn't a good choice for multiple reasons (you need browser instance to configure, naming feels off, you can't set this globally)

• We need to check an important edge-case: what if users followed through with our docs and uses wdio-testing-library? Then if he updates, tests will be failing, because of duplicate commands. We need to check this

• We need to check that timeouts for find* queries are being configured correctly. For example, how timeouts specified in our testplane config, interact with those. If they don't it's an issue, because they should affect testing-library timeouts.

Also, I still see no signs that we respect timeouts set in testplane config in find* queries (see point 3 of my previous comment)

I think now it looks okay, but feel free to ask for more changes
