Notepad++ is an open-source text editor which I found to be suitable for my usage. It has a good plugin extension capabilities, so I used it to create a couple of plugins for my usage and for sharing with other Notepad++ users.
MultiClipboard
This multi-clipboard plugin allows the user to quickly and conveniently perform numerous copy/cut and paste easily via its internal clipboard, and a handy Ctrl+Shift+V shortcut key. This is similar to the excellent Visual Assist’s multi-clipboard function.
All the user has to do is to perform his copy/cut functions as usual, and press Ctrl+Shift+V to open a context menu with the last 10 items that was copied/cut. Selecting the item pastes it into the text as per normal.
Falling Bricks
Derived from mini tetris (which was developed by me), and placed as a plugin inside Notepad++. This gives Notepad++ users a chance for a short break without having to leave the application!
