Help, I need new titles for riddles xD

20/20

Day #31: (look, a month of riddles xD)

(like, seriously, suggest some please, maybe a new and final name for them xD)

Using the first 6 letters of my first name,

I'm put at the end of a sentence.

Use the last 5 letter of my first name,

I'm an acid.

Use all my letters in my last name,

And I'm a furnature,

Yet take away the first letter,

and I can do anything.

What am I?
