I havenāt tested this, play with it at your own riskā¦
In the database, which you can access through phpMyAdmin or similar, the table user_preferences contains one row for that user (referenced in column āassigned_user_idā) that has a ācategoryā column with value āhomeā. The āContentā column on that row contains the userās dashboard settings.
I would copy some other userās āContentā of āHomeā into that row, and see if you can work from there.
It is not encrypted, it is merely encoded. I believe it is base64 encoding, you can try pasting that into an online base64 decoder and see the contents.
Anyway, you just have to copy it, not understand it. You design your Home screen within SuiteCRM using drag-and-drop, when itās ready, you copy that data into other userās, and they get a similar Home screen. Simple.
