#1653 closed enhancement (fixed)

zoom to the previously shown area

Description

I would like to have an additional zoom-function. I very often have to zoom in to a very little area to fix the connection between two ways.

After that I would like to get back to the previous view with one button like '5', instead of zooming out by pressing '-' or using the scoll wheel (which takes some time).

The problem is, that the term "previous zoom" is very hard to define. Usually zooming process has many steps inbetween. Zooming one step back probably will not bring the desired results. There would be a heuristics requirement, which detects the correct level. Very hard to get this right.

the term "previous zoom" is easy to define: simply that area before the last change of the view.

Ok, using this new function makes only sense when using the mouse to define the new view (dragging from one corner to the opposite corner). But this is exactly what I want. I use the mouse to select a very tiny area of the current view, and want to get back to this current view after my editings in the zoomed area (e.g. to control wether 2 ways of a junction are actually connected).

Or, to make it even more useful, in a further step you could define a threshold value, which has to exceed when selecting a previous zoom level. This would help in the case I must slightly adapt my selected area, but would still allow to get back very fast to a previous (overview) zoom level. Overview, of course, does not mean the
zoom : 1 (on all data), but a intermediate area.

going back through zoom-steps is a very nice feature which I really appreciate when working with CAD-systems - this is a feature I miss, too (I sometimes try to intuitively hit <alt>-<left arrow> to go back to the last zoom step or <alt>-<right arrow> to go forward but it doesn't work ;-) 1 step back would be nice, some more steps back and forward great ...)
