Large Dataset
As of SimpleInvoices 2013.1 a new feature 'Large Dataset' has been added.
This has been added to help users with thousands of invoices where the Manage Invoices page starts to slow down. Basically strips out the non-essential info which has complex sql queries that slow the system down.
In SimpleInvoices got to the Settings -> System Preferences page and enable the Large Dataset option ( refer screenshot below)
