Very good work, looks very good your OpenLP product.
I have a bug which is maybe very easy to fix. Easyworship uses tags like Chorus, Verse etc. Also the Tag word itself is a tag. Currently OpenLP imports it as song-text instead of metadata.
We have a large EWS database where this TAG is used often. Can you add the Tag word to the metadata-import rule for EWS import in OpenLP? If a Tag word is observed alone (without other words) it's considered as a remark-line.
