 Notes:
 * Ctrl + X does nothing.
 * muted nodes don't process and block everythintg behind them 
+* Ctrl+C, Ctrl+V, Ctrl+X, work normally inside a text box/field
+* The text areas are like a separate layer. Space and copy/paste functions act normal inside them and use comfyUI functions outside.
 
 ## Organization
-* Add pythongosssss _Node Templates_ [from this repo](https://github.com/pythongosssss/ComfyUI-Custom-Scripts). Download the node-templates file and put it in `ComfyUI/web/extensions/`. (Don't copy paste the editor display, save the raw file.) This repo has some other super helpful extensions as well.
-  * Also recommended is _image-feed_ and workflow-svg

+  * I still recommended _image-feed_ and workflow-svg from [the repo](https://github.com/pythongosssss/ComfyUI-Custom-Scripts)
 * noodles (the wires) can be organized with _reroute_ nodes. It takes extra time, but it makes figuring out a workflow a few days later much easier. Much less someone else.
 * _SaveImage_ can do sub folders. The format is `folder/imageprefix`.
 * The _LoadImage_ node is (at this writing) too small. Drag the bottom down to show the image preview. Glory at the terrible sketch comfy made for an example!
 
+## Filenames
+Output files can be customized with substitutions
+```
+%date:d-M-yy%
+```
+all the variable available:
+```
+    yy -> last 2 digit of year (23)
+    yyyy -> full year format (2023)
+    d -> day number
+    M -> month number
+    h -> hour
+    m -> minute
+    s -> second
+```
+* Put in a `/` to create a folder like `%date:d-M-yyyy%/ComfyUI`
+* `%width%` and `%height%` are also supported.
+* Various items from nodes can also be included. Right click on a node, click on `properties` and use the contents of the _Node name for S&R_ property and the name of the _data_field_.
+  * Example of putting the checkpoint in the file name:
+	<img src=filename01.png" width="50%" align="bottom">
+	<img src=filename03.png" width="50%" align="bottom">
+  * The _node names for S&R_ is `CheckpointLoaderSimple`
+  * The _data_field_ is `ckptt_name`
+  * combine with a `.` between: `%CheckpointLoaderSimple.ckptt_name`
+  * and put that in the *filename_prefix* of the _Save Image_ node
+	<img src=filename02.png" width="50%" align="bottom">

 ## Tips and Philosophy
 
 * ComfyUI has a philosophy of keep it simple. Don't try to create a "do it all" workflow, instead focus on a specific objective.
