@QuaintMako what are your plans for the current BaseLayout, will that be removed?

@QuaintMako what are your plans for the current BaseLayout, will that be removed?

What I aim with this PR is to reduce the duplication inside GridViewBrowser, ColumnViewBase and GridViewBrowser who share a pretty close philosophy. They do inherit the BaseLayout, but so does ColumnViewBrowser who is completely different to the others. That's why I introduced something between BaseLayout and the three classes I am refactoring.

For now there is no plan around the BaseLayout. But looking at it, we may have ways to simplify it.

Opening up this PR for a first refactoring of the different views.
When it's done and merged, I'll look into defining another object between the Grid and Details layouts to reduce even more the duplication of the code.
