One big problem I see is, that power users need something quite different than first time users. You can make some compromise by tucking away advanced features without removing them, but in general it's still an issue.

First time users are probably what you focus on, the rest just has to be a tad better than the competitors. First time users need to be convinced by pretty design and a super simple linear workflow that solves just one problem.

Power users couldn't care less about design (SAP is still alive). They love it feature packed and want to access as many options as possible with few clicks. The extremes are icons without labels, color coded shortcuts on every keyboard key¹ or command line interfaces.

edit: but in the end there is just a lot of bad design, that at best makes things pretty, but often not more useful.

IMO the key point to remember is that power-user modes aren't simply bonus pieces, but different workflows for different needs.

But it's easy enough to initiate those behind menu options, with hotkey combinations available in general... That's how advanced usability options are usually done. You don't have to show it all onscreen at once.
