Some queries for creating partition or subcorpus may take some time (if the corpus is large, or the query complex, etc.) This may lead to a very long startup time at the launching of Textométrie since all the queries defining partition / subcorpus for all the imported corpus are executed at the launching of the Textometrie.
It may be very convenient to have a "open/close corpus" feature, so that, at startup, queries are not launched for the corpus in "closed" state.
