Same here - there are 1000 options, across 15 tabs, and I have to look through all the icons and labels till I find the one, with active tab and even displayed options changing depending on content selection.... It's a constant battle if you don't spend hours a day in MS apps and develop muscle memory.

I do realize that there are probably no ideal UIs for accessing such a breadth of options, and it was a valid attempt, but not really successful, imo. With some adjustment and practice by users, I believe something like Alfred within the app, with smart search and suggestions, would be a quicker and more efficient approach for tool activation. Since there has to be also a good way to discover features without explicitly searching for them, maybe something like the Start menu is the right approach - quick search, but also categories and lists of tools.
