Exactly as it sounds. I select a part of code, search and replace all in it, and it replaces all of those strings in the file. Take look at the video for detail: https://s.savikin.me/fi/2017-03-26_20-41-02.mp4
findbar was not updating search in selection range when the button was clicked, this should be fixed now.
I’m having the same issue. Search/replace function still replaces for the whole selection.
