Hello everybody,
here two of mine suggestions regarding vBulletin CMS:
Primary Content: actually, editing a section, the setting "Content From" can be setted choosing between "This Section Only" and "Include sub-sections". The possibility of choosing also what sub-sections should be used/should be excluded from sub-sections list could be very useful.
Article Layout: actually, an article inherits the layout from the section which it belongs. The possibility to set a custom layout (even different from the section's one) could be very useful.
