i reviewed the spreadsheet just now, a few items have been completed (;ile a off effect besides a none).
most are not implemented.
All of these are enhancements to effects, very few to the GUI.
The focus is going to be xlights 4.0 first. This is a large endeavor and is only happening because dave pitts is willing to put in the hundreds of coding hours to get it started. Dave was working code yesterday on XL 4. My concern is always resources for the xLights project. Come January most of the developers go back to their real jobs and families. Dave works every week of the entire year, but his first love is hardware. He is about half in CL 4 and half in to Pixlite-16 v2 and the Neo matrix driver boards.
Dave has not posted his XL 4 code where any of the developers can see it yet. I am hoping that will happen in the new few weeks. I know he has a functional UI front end, just nothing underneath it yet. Example, you can size, float windows, you can have timing tracks, you can drag effects. There is no play button connected. no effect generation. The target for a functional xl 4 is still 1st quarter.
