A light-weight group communication tool [Experimental]

Slick

A light-weight infinite-whiteboard tool

To do

Immediate next steps:

• Improve drawing quality on Winforms version (better wet ink, commit wet ink directly to tiles)
• Make sure 'undo' works well with stream-db
• Use the 'repeatable' palette, like from the UWP version
• Remove the UWP app, because UWP is so bad.
• Highlighting ink
• Bring the wavelet image code out to its own library and use that
• Erase selected tiles

Possible features

• shared 'infinite whiteboard' inside group
  • 'strands' to loosely link conversations
  • 'bubbles' to tightly link conversations
  • a way to push off-topic or humorous chat aside without removing it
• peer-to-peer audio/video link
  • try the 3D CDF wavelet thing here?
• Non-euclidean surface -- as you scroll away, content is reduced but not hidden.
• Android client

slick's Issues

Tile visual cache sometimes desyncs (UWP)

Maybe ditch the UWP compositor and move back to a single element that is draw by the app?

Scrolling is very slow when zoomed out

Seems to be a speed issue with the image decoding

Undo is not reliable under StreamDB

Often too much is rolled back. Check the reset points are being used correctly. Check that garbage index is unhooked if needed.

Also, look into a more general and robust version scheme.

Add text box to UWP version

Like the WinForms version has

Pinch-to-zoom

Add a zoom-in past 100%
Use the new scaled image import code, allow drawing between 0.75 and 1.25 scale?

Show version number and filename in the title bar

Highlighter pens

Highlighter should be a separate subtractive layer of the canvas

Clear-down canvas option

Probably don't need to wipe the whole thing, as that can be done with a new file.
Might be useful to select a region and erase it all.
