Pros & Cons from Real Users Pros It's free and open-source, extremely fast start-up times, uses very little memory, and surprisingly customizable (I barely did any myself though; I wanted to keep it light). I find it useful for swiftly taking notes at a moment's notice, but I have also used it to quickly peek through config files, source code, or even certain text documents--they all just work. As a user who swaps between Windows and Linux, it being cross-platform is such a huge plus for me, and is the leading reason why I use it over Notepad++. As much as I like tinkering with software and hardware alike, I also don't want to find out that certain features I use regularly on one OS's notepad don't exist on other OS's notepads, even some third-party ones. It's just some peace of mind. Cons It lags for ~1 sec when it wraps text for the first time since the app was opened. Even after using this app for over a year, I still find the logo hard to identify as a text editor of any kind. I still have to tell people who borrow my laptop that my notepad app is this, even when it's pinned to the taskbar and start menu.	Pros & Cons from Real Users Pros I'm not an HTML / CSS/ ... person, but I have built and maintained my personal sailing / nerd web pages (40 different pages, and counting) for many years, using only SeaMonkey Composer. WYSIWYG make it super easy to use. And free. I don't use the other SeaMonkey tools, just the editor. It is the successor from Netscape, so lots of history. Complete suite of applications for internet usage Free to use Lightweight feature rich browser based on Firefox Email & IRC Chat client Composer - powerful HTML editor Regular Updates Large number of add-ons, themes & extensions Great community support Cons I'm sure there are better and more modern tools for making simple web pages, but none as easy and cheap as SeaMonkey. I can't make fancy, active web pages with it. I use external blogs for that, and just include links. Same with Youtube videos. It is excellent - simple and powerful - for those who just want pure functionality. It is not widely popular due to its old look and no marketing.
