How to edit theme in a easy way

Hello, I’m looking for a way to edit theme for suite crm with custom icons for menu and tabs for like histroy, documents, activities,
And a hole other customized frontpage for suite crm .

Is it possible to do it? Or do it exist any kind of theme maker for suitecrm ?

Of course it’s possible to do it, but you will need the development know-how.

There is not currently a theme builder or maker.
