Sure wish there were a way in Integrated Library and Online Search Mode to search and find an item without adding it to my library, that is, to place it in a separate holding place as it does in Procite (and also where it would not disappear unless I wanted it to.) I often want to do searches and then select just one item to place in my library, while retaining the other search results.
The workaround I have found (setting up a separate Search Library or switching between Online and Lcal Library mode) involve extra mouse clicks at best.
