The Sage 50 UI feels really outdated as far as editing capabilities. I've already requested a spell check feature, and there's another feature that would improve Sage in terms of efficiency. For users who make very detailed invoices/orders/quotes with many line items, editing can be an extremely tedious pain because of the UI limitations. For example, sometimes it is required to delete or copy and paste many lines in a quote. Currently, the only way this can be done is selecting each line at a time, clicking the tool bar, and click 'remove line' or copying it. It would be much easier, and more in tune with modern applications to be able to select multiple lines at once, for example by using <CTRL> and the cursor keys or mouse to select multiple lines, then right clicking and selecting delete, copy, or cut.
