Answer 1

In the Project View click on the "gear" icon and enable the Open Files with Single Click option:

Use Ctrl+Q for Quick JavaDoc and Ctrl+Shift+I for the declaration pop-up.

@SimonBengtsson Coming from Sublime, this is the feature I crave the most. – Ciaphus

@Ciaphus you stole my words... I really thought that was addable – Edra

@SimonBengtsson Get rid of tabs altogether! You won't regret it! I tried it and I'll never go back. You can easily switch "tabs" using Ctrl/Cmd + E. Couple it with Zen mode and it feels super awesome ;) – Poona

@SimonBengtsson Enable preview tab may do the trick. https://mcmap.net/q/209535/-how-to-set-single-clicking-to-open-file-in-intellij-idea – Bunting

Answer 4

Javadoc opens with Ctrl+Q

There's no declaration view per se, however, you probably will be satisfied with Ctrl+Shift+I shortcut for quick lookup.

Don't know of any ways to configure it to open files on single clicks. Somehow, if you get used to the shortcuts, you skip using mouse very much. For instance, Alt+Home will bring the navigation bar up and you can move with arrows and open the file with Enter. Or just use some other shortcuts like Ctrl+N or Ctrl+E depending on the context.
