Currently when I remove an column from a layout grid, the other columns weight stay the same. This results in an error and some manual correction is needed from a develper.
I feel that this isn't always needed. In some situations a sort of 'auto-correct' mechanism would come in handy. For example: when i have 4 columns with a weight of 3 and delete one, it can make sense to autimatically scale the 3 remaining columns to the weight of 4.
There are cases in which this isn't always desired. You could want the columns to be manually edited so they have weights of 3,3,6 for instance. Therefore can imagine something like 'Enable auto adjustment' (or something like that) as a property of a layout grid
