A formal release will soon be placed in the Files area as well.
Under some (unknown) circumstances the preview becomes a blurred, grayish field. This was due to using PNG as the image format for the preview. Switching to JPG solved the problem.
Note that due to the JPG compression there may still be some blurring. If you do not have a problem with the PNG format, you can keep using it through a toggle option in the File menu.
Fixed a cut/copy/paste bug.
The "java -jar tintfu(version).jar" style execution now works.
Now features an Edge List Editor.
This beta version is functional but does not yet contain all features I have planned. Still, it is already pretty powerful as is.
