lock margins values so they will not be affected by gridder defaults

[dmncn]

I usually have the same page margins all over a website, expect for the pages where I enable a Cover and where I need to set the Top margin to 0.

If I update all values in the Gridder Defaluts for all pages, then I need to set again to 0 the top margin for all the pages containing a cover image.

It would be nice to have in the Gridder, next to the Top, Bottom, Left and Right, a lock icon that means that it doesn’t affect that value when applying gridder defaults again.

Also, the Gridder Defaults page could be much more well-ordered if % and PX would be at the right of the values, like on the Set Frame pop-up in the Gridder.

yes those are good ideas, writing them down
