Q:

Hide some devtools tabs in chrome

How can I hide following tabs in Chorme devtools?
I know that I can reorder them, but I'd like to minimize extra interface part for some competition.

A:

There is no solution to this. You can't hide certain tabs in chrome devtools.

A:

This is certainly possible! But it isn't trivial. You need to create (or find and download from the Chrome Store) a Chrome Extension that themes DevTools. If you create one, one option is to find the elements by inspecting DevTools with DevTools itself and then use CSS to override.
This great answer to another question on the same topic was extremely helpful to me: Custom.css has stopped working in 32.0.1700.76 m Google Chrome update
