Adding a 'Replace then Find' function (or just changing the current replace button) in the normal (CTRL+H) function. I see it's in the advanced (CTRL+R) but regex doesn't work there yet (And it's messy for simple find/replace)
while in (ctrl+H) window
e.g. If I'm search for all tabs '\t' to replace with ' \t ', when I push Replace, it should replace the current found '\t' then find the next '\t'.
