How to add a "property" to a topic ?
I'm using Mindmanager 2022 and I try to do something but I can't.
I would like to add a "property" to a topic.
For example "tCO2eq" to tell how much tCO2eq the task which is associated to the item produce. Its a bit like the Progression icon but with a more precise value to specify.
How can I do it ?
Thank you for your help.
