# simplify and latex_name

In a notebook (with typesetting enabled), whenever I apply simplify to a simbolic function, the result is expressed in terms of the identifier of the function, rather than its latex name.

For example,

```
var('x')
my_func = function('df',x,latex_name='\Delta f')
my_func
```

returns ?f(x)

but

```
my_func.simplify()
```

returns df(x)

Is there any retain the latex name throughout simplification?
