Love Koreader, I'm using it almost daily can't live withot it

(and K2pdfopt as well)
but I'm a bit worried for this to become bloatware sometime in the future.. I love the idea of plugins since anybody can simply delete the features he doesn't need.
But as I have the old Kindle (1,5 gb) space is always precious for me. Not a programmer myself but please make as much features pluginable as possible - so that the software does not grow to much for those of us who love simplicity and stability over full feature rich suite. Thanks!
