My friend sent out her application in mid January this year.
I am not sure if the form has been simplified or not yet. Depending on how confident you feel about the progress of the negotiations between UK and EU, you may want to wait until the UK releases its plans for EU citizens and a possible 'settled status'.
It was mentioned a few weeks ago that even EU citizens with permanent residence would need to apply for settled status, although the process would be simpler for them. This might mean an additional cost over and above what was paid to apply for/acquire permanent residence.
Good luck!
