Respect flexinode types in search form

Well, flexinode search is really great, but unusable for many flexinode uses as it doesn't support more flexinode types.

When i downloaded flexisearch, i assumed it will render form, which will respect my flexinode content type, such as:

I have type "FooBar" consisting of:
1. textfield named "Groupname"
2. checkbox named "From USA?"
3. multiselect menu "Language" with options "English, German, Czech"
and so on

then flexisearch form should not be rendered as:
Groupname: [_____________________]
From USA: [_____________________]
Language: [_____________________]

But as:

Groupname: [_______________________]
[checkbox] From USA
Language: [select]English German Czech[/select]

This will be true flexisearch rendering it as "parameters" search.
Do you think this is good idea? I will try to submit a patch to flexisearch this week, should it be a part of flexisearch or should i create separate Module for this, as "Flexinode parameters search" ?
