The KDE dev disagrees with this premise, thinks that additional clicks don't matter much in the grand scheme of things,
I know I would.
In a traditional WIMP GUI app, you press Alt and automatically there is a letter in the menu underlined. That means that pressing that letter in the keyboard, you get the menu pulled down. Then, you can navigate it using cursor keys + enter or other highlighted letters.
This is no longer possible with most hamburguer menu apps in Plasma. You MUST use the pointer device (mouse). That is my pet peeve. More or less clicks is not really of the essence.
Apps doing this need fixing (and can be fixed). In Dolphin:
- F10 opens the hamburger menu
- CTRL+M restores the traditional toolbar
- you add the button you often use to the toolbar
- you use the keyboard shortcut, that you can customize
