We're working with cutting edge technology and the best we can do for this is a new tab for giving merit? We really do not need a new tab just to give merit.
There is an advantage to the way how merits can be given currently.
When you click on merit, a new tab opens and you are asked to input merits and then send. So, it is kind of confirmation that you really want to send merits and double check on how much you want to send. I think admin could easily integrate what you are suggesting but he might have kept it this way intentionally.
