actually when respo was released i was able to "use another" on my small first aids too but then it disapeared. probably just a bug.
i've since donated my sfak's to the faction and there alot quicker to use there. the use button and the "confirm" button are right next to each other and after a few clicks you'll get the hang of using them nearly as quick.
Instead of clicking the "close" button, you can just click on the take icon again to save yourself the extra click. It's just one more click than the use another button til that, hopefully, gets restored.
