It's a limitation of libkipi. in fact, i would implement plugins
progress handling in host application...

It's in my to do list for the future.

Not reproducible here with last code...

No. on icon item where hover rating overlay appears. It's the same
behavior in Gwenview about rotation.

This point is fixed with my last commit. only icon where rotate button
is pressed will be rotated.

Pb : is selection is done before, it will be lost. kipi-plugins only
work with selection, so i need to deselect all and select only item
relevant before to run plugin.

It's a limitation of libkipi interface. this must be improved in the future.
