And are there any plans to have a 'named filter' control within widgets that would let you change the operand?

It is possible. There was the question regarding this option.

If you need the filter for the measure, make it searchable, as Peter said. 

If you want to filter calculated measure, try to change it to classic measure with COS expressions in the measure definition.

Hi, John!

I think it refers not only the "importing xml" cases but also any installation of any 3rd party tool or solution to your target InterSystems Caché or Ensemble server. 

I think the Package Manager can cover some risks in this field.

Another idea relates to docker technology: install the "unknown" but interesting solution into the docker container first and see how it works and where it tries to send the data and etc.

Alexander!

For Categories  Overview it tells me I have 2 selected items but under Categories tab I have 0 Tags and The groups section tells me it is restricted and  I do not see any tick boxes on the page.

2 for categories it is a bug we are fixing now. Every member has it if there is no any subscription.

Just before your update I received and email entitled "[ISC-DC] Encoding issues ..." which is an issue I am not explicitly trying to watch. When I click on the Purple Unsubscribe at the very bottom of the email. 

It seems it's a bug. We'll try to fix it.
