Building Form features

I have some feature suggestions for building forms.

Regarding checkboxes and radio select it would be helpful if you can have an option of 'horizontal alignment'

When I have put in a lot of options horizontally I want it to be aligned (Sometimes I specifically don't want to do a vertical checkbox list or radio select list and I can't add characters to align it. Please see screenshot below)

It would also be helpful if for checkboxes and radio select - there can be a Field name and then Subtitles. 

For example;

Hair Color: (Field Name)

Dark (Subtitle)

• Black
• Dark Brown
• Brown

Half Blond (Subtitle)

• Light Brown
• Ash Brown
• Honey

Blond (Subtitle)

• Golden Blond
• Strawberry Blond

In addition to these features, I have some more feature suggestions. 

In a multiple choice field, when a person completing the form selects 'other' it's neatest if every time throughout the form there's a field  called 'please specify' for them to describe what 'other' is. But I can't have more than one field with the same 'field name' is there any way the field name can be the same but it has a 'backend' name.

Also, if when the person selects other - under the word other should be a text box for them to describe = inline typing.
