LocusMap or LocusMapPro is required for usage.

To start modification click on any POI in Locus Map application and open its Details dialog. Then open Share menu and select LoPOI plugin.

To download POIs for current location open Locus Map menu and select this application from Add-ons list.

Q&A:
* Do I need installed map with POI database?
Yes and No. With POI database you'll have an access to all features of the plugin. Without POI database you will be able to create new POIs. Modification and deletion of existing POIs will work only if you know POI Id (that is not convenient).

You also can download POIs around specific location using this application and modify/delete downloaded POIs.

* What OSM elements can I edit with LoPOI?
Modification & deletion support Node and Way elements. Creation supports only Node element.

* What data can I edit in OSM elements?
You can edit only tags.
