Well, my previous post had too much technical stuff that most of you don't care...
And, I forgot to mention the most important point of the post.
The most important decision is to combine "KG-Chart" and "StitchSketch" together.
In reality, KG-Chart's code base is going to fade away, and the "StitchSketch" will become the main application.
StitchSketch will run on all major platforms based on my cross-platform library, which I explained in the previous post. Because it runs on MS-Windows, KG-Chart no longer needed - StitchSketch will take over that position.
StitchSketch will be able to open files created with KG-Chart.
Existing KG-Chart users will be able to use MS-Windows' version of StitchSketch with their license key.
Hopefully this plan will work...
