Swift version 2.5 is available;
http://www.retrosoftware.co.uk/wiki/index.php/SWIFTMain addition is the in built sprite editor.
Only supports mode 2 at present and a limited set of editing tools. But a new version is being worked on that will add extra modes and features.
As always a video demonstrating the use of the Sprite Editor is available (Tutorial 8).
I was going to add a screen shot here but don't know how to link to just the image loaded up in the WIKI. Tried a few things none worked. Anyone know how to include an image uploaded to the WIKI in the forums ?
