I build many projects within Workspace.
Every project often has several panels when trying to compare date ranges or single out dates within the analysis in a way that doesn't affect all freeforms within the panel.
It would be helpful if we could move Freeforms from panel to panel, have that flexibility in order to save time when building custom report for certain clients that only want to see some information.
Great suggestion - this is definitely on our roadmap. In the meantime, you can duplicate the existing panel and then delete the other visualizations in the newly-copied panel. I know this won't always do what you need (ie, moving a visualization from one panel to another existing panel), but it may help you in some situations.
Can this one be marked as closed now that Copy-Paste is enabled among panels and projects?
