I just testet this tool on my phone and have two ideas for improvement:
Add (temporarily?) ignore button. If I am unsure about an OSM Object, I dont want to edit, I dont want to open a note, I just want to get to the next object to edit.
I was not logged in, then pressed upload. I was told I cannot upload because I am not logged in and I have to log in, but there was no log in button visible.
The login button is at the top of the page, but I realise it would be more useful to be also on the upload dialog when you are not logged in. I’ll add it there.
I think it would also be nice to split the first section into duplicate data and fix issues. Most cases are where name needs to be duplicate to the missing name:lang field. But I would be more interested in the mismatches, where name does not match name:lang or any other issues. Thanks :)
