i regularly use regular expression. however small but important feature is lacking on emeditor. that is regular expression combination backup which i would use whenever need. because at the moment, original one and replaced one are shown at pull down menu, but that is not reliable, and once close replace window, regrex combination i would use again is lost or not one i would intended. so i would like to see at save bottom at replace window so as not to repeat input regular expression time and time again. its feature already exist at another editor viz. jedit editor on mac osx and i found very handy. i sincerity hope this regular expression combination save feature sooner than later.
