For options I change often, I use the following to
display its value in the statusline. 

function! OptSet(opt, string)
   if(exists("a:opt") && expand(a:opt))
      return a:string
   else
      return ""
   endif
endfunction

Then put the following in the statusline:

set statusline=%<%f\%h%m%r%y%{OptSet(&ic,'[ic]')}[...]
                             ^^^^^^^^^^^^^^^^^^^^

So in this specific case, if 'ic' is set, I will
have '[ic]' in my status line.

I use that for 'ic' and 'ws' because I toggle them
quite ofen.

HTH,
