Find in ISE needs to be able to wrap rather than stopping when it reaches the end of the file
Find in ISE starts from the cursor position and stops at the end of the file. This is extremely annoying behavior since to perform a full file search you need to move the cursor to the beginning of the file before beginning "Find".
Find needs the ability to find within an entire file from anywhere the search is started -- just like notepad++, notepad2, and any other modern text editor.
You’re right, that’s really annoying. We’d like to do it as some point in the ISE Preview: https://blogs.msdn.microsoft.com/powershell/2016/01/20/introducing-the-windows-powershell-ise-preview/
