This software is easy to use thanks to its tags feature where all you have to do is click one button, enter the text you want displayed, and voila! Not only that, it also has wizards that make creating tables and other visual elements a breeze. It does have one drawback - no WYSIWYG, so no live previews of your html files.
I've recently started using it to edit a web app, and even though it might seem like a simple feature, the mini file browser on the left that lets you open files to edit is a godsend. I was using Notepad++ on Windows, and never realised how often I was switching to the folder and back.
I've since switched to Geany, which has a terminal section at the bottom of the program window. The main reason I switched from Bluefish to Geany was because Geany had 64 bit compatibility with Windows, and I had just got a new Windows machine (an HP laptop) to replace a Linux machine that didn't work anymore (an old Sony VAIO.)
