I run multiple sublime instances and I use the “Window” menu to switch between the different projects. I run the same sublime project name but in multiple different folders. If sublime is showing a normal file then in the “Window menu drop down” it shows the full path to the file which makes it easy to choose which window to switch to.
Now if the project is showing the “Find Results” then there is no information about the path to the project and makes it hard to choose which window to switch to (for instance if multiple projects are showing the “Find Results”) window. See attached image as an example:
