Hi. As a new respondent to the JuffEd project, let me introduce myself with much praise for JuffEd. You might enjoy the anecdote: I have marked JuffEd, in my local downloads repository, as an editor which is "a perfect balance between features and functionality". What I mean is I find the editor not to be over bloated with crowded menus and configuration options, yet JuffEd provides enough custom configuration for the user to feel at home working in the environment. Very well done; great job!
Regarding the topic of Regex, I'm referencing the 0.9x development edition. I'm not thrilled with the implementation of the search facility, in a fixed position beneath the main editor component (however, I do not doubt-- i could be wrong; maybe i haven't figured how to move it?). Also, I don't see any configuration to use regular expressions in a search / replace feature. Again, maybe i'm wrong (i apologize, i haven't compared/ contrasted with v 0.8x), but I thought regex search / replace is a function of the previous edition, and the search facility is a floating window (i.e. more like the search-in-files function of the development release).
Best regards, and good luck in the forward progress of JuffEd!
