Two levels: this board (overview) → click any card for the deal detail (next level). The detail keeps Zoho's depth but drops the clutter: a stage stepper up top, deal properties left, a working activity/notes timeline centre, and — the IBS edge — a full live Customer 360 on the right (trajectory · Xero AR · last jobs · lifetime value), so the rep never leaves the deal to know who they're dealing with.
