Atm I'm using two complete sets of group bars, one static, one roaming, which are a little difficult to maintain. Could you perhaps add a template based group+party system, much like the one for scenario / warband groups?

Or, to safely allow multiple group bar sets, 'bar sets' that I picture like this: a creatable entry that contains the link to the used bar template + the range of adapters to apply it to plus some settings. This could finally even succeed the current wb + scenario system.
To create a set of scenario group bar, for example, you would first create a bar template, then add a bar set using it, setting up an a range from <scenario group hp #0> to <scenario group hp <#max>>. Or multiple for each party within, if liked. Finally perhaps a position dialog, with options like 'roaming' or 'stick to predecessor/successor' + anchor points.
Imho this could blend in pretty well with the surface + concept of HUDUF... mighty + customizable. Also it'd mean a lot of work... so np if I get a simple 'can't do' answer. ^^
