When creating templates in Lucidspark we have the ability to categorise the template we are creating.  The following options appear when doing so:

If I select a sub-category such as 'Project Planning -> Retrospective' as the category for that template then you seem to lack the ability to see that template sub-category in the Template View when inserting into a new board. i.e. You can only see your template appear in the 'Personal' category - with no sub-categories being displayed below that node: (in the s.shot below 'Agile Development' is being used for other templates hence the reason for it being there)

Wondering if this feature will ever be added?  Currently starting to share templates between team members (notably retrospectives).
