Just a few thoughts about how the Roassal Easel [Examples] are presented.
Some text describing the meaning of the blue and pink grouping boxes would be useful - but to hazard a guess blue is the replicated Mondrian functionality and pink is the new Roassal functionality ?
The ZoomIn and ZoomOut buttons don't work with either the [Examples] of [Info] displayed - which is fair enough, but there is no feedback to indicate the buttons will have no effect. This is quite nit-picking so perhaps can be ignored.
Once any particular example is clicked, there is nothing that displays what the current example is - so if (like me) you forget which it was two seconds after you click it, you end up a bit lost. It would be nice to have something that identifies the current example.
Example>interaction>leftAndRightClick - fails Example>interaction>clickAndMove - the element ends up about 150 pixels below the click. It should either centre or align a corner with the click. Example>colors>normalizer - it is not clear what the purpose of this is, especially under a colors section - it is just an empty black box that is moved around.
