I have some suggestions for improvements:
- Search window: add a tick box to select articles you want to import since you may want first to read through the abstracts before deciding which articles to import
- When importing a book allow ISBNs with dashes in the corresponding search field as this is the form they are found in the first pages of a book (e.g. 978-3-319-72961-9)
- Enable an OpenURL search from within a PDF based on the text selected (to lookup a cited article)
