+A Krita plug-in that runs an external application on a single paint/clone/group/file layer.
 
 As an Adobe refugee, I've moved to Krita for my photo editing. The only thing I missed was the option to run Photoshop plug-ins on a Krita paint layer. Often, they can be used as stand-alone programs, but I quickly got tired of exporting a layer from Krita, starting the plug-in, edit, saving the file, and importing the modified layer into Krita again. That's where this little plug-in comes in handy.

 ## Notes
 
-- The plugin requires the data format to remain unchanged between saving and loading of the layer. For example, when working in a 16-bit environment, ensure that the external editor also saves the layer file in 16-bit format.
-- The dimensions of the layer (width x height) needs to remain unchanged
+- The plugin requires the file type to remain unchanged between saving and loading of the layer. For example, when a layer is exported as PNG, it needs to stay a PNG. You can change the bit depth to whatever is supported by the file format, as long as it is supported by Krita.
+    - Integer formats are exported as PNG.
+    - Float formats are exported as TIFF.
+- The dimensions of the layer (width x height) may change, but the layer size will change accordingly.
