Can we add support for this?

Hi Meni,

Column settings are persisted as part of the parser configuration.  Files which use the same parser configuration will share the same column layout.  Modifying the parser configuration will reset the column layout.

So, the only way to achieve this at the moment is to reuse your parser configurations more widely.  Auto-generated parser configurations are not particularly good at supporting reuse, so there may be an opportunity to consolidate.

Hope that helps,

Toby
