Notepad++ is a powerful text editor; so much more than a Windows Notepad replacement, and (for me at least) often better for 'real' word processing than Microsoft Word, when coupled with language tools (like Markdown) and plugins.
One of the powerful features in Notepad++ is the Plugin Manager, which provides an easy check-box menu system to install a wide array of plugins that enhance the program. This way, you don't have to mess around with finding and downloading add-ons - it's easy to get them right from the application.
I've had trouble mounting SMB/CIFS External Storage recently in OwnCloud (currently version 9.1). External storage mounts have always been flaky in OwnCloud, but this time I think I found a solid solution.
