Transparent Sublime Text 3 at least on Windows
There are sometimes when you like to read content behind your code editor, specially snippets, documentation of APIs or other important stuff that sometimes requires you to switch between your code editor and that documentation (webpage, pdf, etc.).
And that is why it is sometimes useful to have a translucent code editor, and if you love using SublimeText3 editor, you might know that it doesn’t allow you to set its opacity level, so you might end up hitting Alt-Tab hotkeys or adjusting both windows side by side in order to copy or read a documentation without hassle.
Anyhow, having a little knowledge about Windows APIs gave me the idea to change the application’s alpha opacity level, and since most applications running on Windows let us do it, it is only matter of coding now.
