And with some others, politeness and objectivity in the discussion have a lot of room for improvement.
But on the web 
To each their own. That should be possible as far as I’m concerned, but preferably not as a button. There are zoom buttons on the web, but zooming is much faster with the mouse wheel. And an undo/redo in the “right-click menu” is right at the mouse pointer, so I don’t have to target a button first.
that just crossed my mind
The browser context menu already has 10 entries; adding 2 more doesn’t make it any clearer. And where are the buttons in the app supposed to go? Consistency!
2 small buttons next to zoom buttons take up 0.0% of screen real estate on desktop.
Another question is why the usual shortcuts ctrl+z and ctrl+y don’t work in the desktop version. But at least there is the somewhat inconsistent “backwards navigation button” workaround.
And in the app, on the other hand, there’s no alternative to the buttons hidden behind (repeatedly) 2 taps.
And above all, it’s a context menu. It interacts with the context under the pointer—meaning a point on the map. Undo/redo has no business being in that menu.
OT … I mean, just looking at what I “don’t know” through the UI, he’s right and there was nothing unfriendly about it either #m2c but others see things differently.
