What I did:
I created saved Tag searches
What happened:
They appeared on Overview
What I expected:
I want to change the order of the saved searches, e.g. #Important, #Someday as first.
Things that might be helpful to know (Agenda version, OS and model, etc):
Latest Agenda MacOs / iOS app
We don’t allow manually ordering of overviews or projects yet, but it is high on our list. Should be coming along sometime soon.
Any updates on this @drewmccormack? It’s been a little over a year. 
Yes. Projects and categories can now be reordered, and categories can be nested. Overviews still cannot be. That’s a future project.
Just bumped into this limitation, so +1 for being able to manually order overviews. Thanks.
@drewmccormack I also miss this option. Is this coming with Agenda 19? 
Probably not 19.0, perhaps v19.1 or v20 but can’t promise things yet.
