I applaud the initiative. To be honest, I never understood why this was left to less-than-cooperative third party.
Using:
FPC 3.0.4
Lazarus 2.1 SVN rev 62735
Windows 8.1 64-bit
The following are not criticisms, just my observations.
Works mostly as expected for me, but there are issues.
* The Form never gets a selection rectangle/rubberband/doodad. (I don't know if it should, but it seems off to me).
* Title bar does not render BorderIcons or other decorations.
* I cannot activate the form in the object inspector by clicking on the title bar (pressing escape works though).
* Title bar makes no effort to emulate the appearance on Windows using system metrics/font/size. (Is this is a cross-platform issue?)
* Using Tab or Shift-Tab keyboard navigation moves to controls that are not visible on the form.
* The last is just a thought... move the toggle for the preview pane to the unused area between scrollbars. This would allow the button panel to be center aligned to the preview panel. Lik eI said... just a thought.
It's a really good start.
Can we expect IDE Docking in the future?
