Image or file count

At the bottom of the Window menu you will see a list of all open documents. However, the documents are listed by file name and the menu does not give you a total count.

A script was discussed at

https://community.adobe.com/t5/photoshop-ecosystem-discussions/how-to-tell-how-many-files-are-open-without-counting-them/m-p/9394679

It isn't clear to me where you are suggesting this feature request to be placed. Certainly not in the Info panel, as this is for individual, document-specific readouts. Where this would make more sense is down the lower left of the interface in the status bar where there is also an option for layer count among other info.

A script can do this for you until Adobe possibly adds such a feature. You can install it and bind a custom keyboard shortcut for easy access:

alert("Open document count:" + "\r" + documents.length);

or

alert("You have " + documents.length + " documents open");
