TFlowPanel controls Fill remains space on waForce

[ϻαϻɾΣɀО]

Hi everybody
Today I`m working with TFlowPanel after a while and it seems functional, But it would be nice with more things to provide Integrated UI with less configuration.
At first one more Option (waForceFill) on WrapAfter options, So last control at a line with this option fill remain space
  Same as attached image, on right FlowPanle, Edit controls fills the remains space of the Panel!
And PaddindX, PaddingY for spacing between controls that added on it. I know the Border spacing of components do it, but with these ones we dont need change them while changing RTL/LTR in my case!

I would use this for automated form schemas.

I will do these chnage by myself,
Even some same patchs on old version of the Lazarus or Right and Left position of TPageControl in gtk2 and more, That some of Solved on last versions of the Lazarus, But I dont know how to  deliver same things to the Lazarus team.
