I wonder whether there is a need to have search bar without diving into particular app. So, if I don't remember which app has vendor bills I can go to search bar and check. Then system can offer all the places where I can find vendor bills.
The second question related to data stored in the system. It could be useful if I'd like to find all the documents related to particular customer, for example. So I can go to this data search bar and enter customer's name. Then system can give me list of all the documents related to this customer.
Do you think it could be interesting for you or your acquainted users to have such tools?
