Supply a search-and-replace facility for PowerApps Editors

This follows on from @rbunge's suggestion to provide Find (CTRL+F) functionality (https://powerusers.microsoft.com/t5/Power-Apps-Ideas/CTRL-F-find-ability/idi-p/759394).  The automatic ability to change references to PowerApps screen artefacts (screens, forms and other controls) is very welcome, but when creating PowerApps, it would be useful to be able to alter references to code objects as well, such as Collections, records, and scalar items (string and numeric context and global variables).

Excellent idea! All in the name of efficiency and accuracy... Very nice.

Essential for more complex PowerApps; we need to be able to do for objects (especially Collections) what is currently supported for Variables, that is see where they are set and used; even better to globally rename

This would be awesome. Please get this done.
