@Andrew Heard: thanks, but .. you know ... it's needed to simulate this problem, so if you find something useful, please let me know.
@joeloc: thanks for a feedback. You are same as @voldapet . One day before release, he, same as you, write me essay what should be changed in this new "Map items" screen. Well, nice thanks. Anyway I do not understand, why you write it day before release when this feature is in Locus for testing almost two months!!! So sorry, but to next version, there won't be any serious changes.
To your problems ... quick return to map and back on same place ... use small bottom left "home" button. Loading dialog ... yes it's there, same as in previous "items" tab. Neverending story with cumberstone UI that break fluent work etc. ... I know, don't worry.
Anyway feature is in active development so I register these issues, thanks.
