Snip

SnipAway has a very advanced internal editor which you can also customize to match your style. It also has some very useful features like autocomplete, syntax highlighting, code folding, and multiline selection. Folders allow you to group snippets together using a color and a folder name. Using folders you can also group snippets together no matter what the snippet language is. For example group all snippets for a certain project together using one single folder. You can easily create a Markdown file and use it to write down your ideas or quick notes. The markdown file will act like every other snippet file so searching, editing and assigning to folders is no problem. When enabled language icons allow you to directly see in which language a snippet was created. This allows you to find the snippets you are looking for more quickly. If you don't like this feature you can still of course disable it in the settings.
