Right now there is only one check-box that clears ALL translations from the database
This cleans only translations which are in database but are no more used (for example, if you translated some strings from a plugin that you no more use).
I don't see how to do. What if you want it back?It would be nice, and not to difficult, i think, to have a button to remove individually entries from this list
I am planning to improve the situation in (probably in v1.1) by adding a way to group strings and a way to filter them by group (more or less the same way WPML does).
