Effects would be useful for Cells too. The
Effects property is on
Cell inherits from, so you can add an Effect to your Cell, but it is ignored because it was never implemented.
As Cell already inherits from Element and Element has the Effects collection, the API is already there.
See the Effects documentation.
This is obviously a bug to me. If the API allows something, but it does not work, then it is a bug. So I filed bug 39739 in February 2016. Yesterday @PaulDiPietro commented on the bug that I should raise the topic here.
Shall I open a topic in the Evolution forum to suggest that each of my bugs get fixed?
Would you please clarify when to use the Evolution forum, UserVoice, the forms-devel mailing list or anything else. Because I really don't understand it and I'm sure I'm not the only one. You can add that clarification to your Please Read First post.
When I first read about the Evolution forum, I thought that it would replace UserVoice (because you clearly don't care about UserVoice at all). But @pierce.boggan tweeted otherwise. The forms-devel list was good in the beginning, but doesn't seem to be used anymore.
Don't get me wrong, I think this forum is better than either, but then you should officially close the other options (and migrate open topics).
