I'm trying to understand how the maps work before I start editing (inserting)anything!...
Firstly, as I zoom in on a section of map, a town name - say Hungerford, UK - appears visible, then disappears, then reappears depending upon the level of zoom. The same is true of features such as Locks on the Kennet & Avon canal west of Hungerford, near Crofton.
Is there a way of ensuring (at editing stage) that a feature will remain visible at all the zoom points up to maximum zoom?
Also, is there a way of having a feature's tags display in the View page when my mouse hovers over or clicks the feature I'm interested in?
