[Feat]: a different icon for a custom dashboard

[andrewm4894]

Problem

a very minor one

if i have a dashboard with same name as a node then its not quite clear which is which - might need a custom dashboard icon to differentiate them a bit more

Description

maybe a icon specific to custom dashboards would resolve this

Importance

nice to have

Value proposition

1. a little bit clearer what tabs are custom dashboards and which are single node views

Proposed implementation

No response

@christophidesp this is something you could probably take a look when you're back
