Add the ability to manually delete trash records. The way it works now it's all or nothing with no context as to when a record may have been deleted.
Prompt for confirmation when deleting a record (regardless of whether in trash or not). Do you have any idea how many times I've accidentally deleted a record? I don't either because there's no confirmation! /rant off
Add a status bar indicating how many records appear in the current view and if any are selected, how many. (Just like Windows File Explorer.)
Add an option to make it easy to report websites where 1P doesn't work properly. It should be as simple as clicking a button, answering some questions (possibly some pre-defined and an input field for notes) and send the info over to Agile. Agile can use this information to monitor trends and prioritize fixes. Agile will also know if something previously reported and fixed is broken again.
Add an option to clear ("X") find dialog. Move the "include notes field in search" option closer to the find text dialog box so the feature is more obvious.
