262	Deleting a layer with modifications	mihau	josm@…	"When deleting a layer containing modifications a warning message should be displayed - e.g. similar as the one when exiting the application (Unsaved changes/There are unsaved changes. Discard the changes and continue? Yes/No)

- create a new layer
- create some elements (e.g. nodes)
- delete the layer => layer get's deleted without warning message

It happened to me twice by pressing delete button instead of hide."	enhancement	closed	major		Core	tested	fixed	GUI, usability
