The free Text Sharp extension lets you adjust text clarity in Visual Studio 2015, Visual Studio 2013, Visual Studio 2012 and Visual Studio 2010 IDEs (Professional, Premium, Ultimate and LightSwitch). You can select Aliased, Grayscale or ClearType text rendering mode for Visual Studio menu, tabs and editor windows. An easy way to turn off ClearType. (Aliased rendering looks terrible when text scale is changed from default 100% in text views, so Text Sharp doesn't override VS settings when Aliased+Display is selected and zoom level is not 100%.)

1. Improving the development experience when using popular JavaScript libraries
2. Adding support for new JavaScript ECMAScript 2015 (also known as ES2015 and formerly ES6) language and web browser APIs
3. Increasing your productivity in complex JavaScript code bases

 Its value MUST be a number containing a NumericDate value.

 A JSON numeric value representing the number of seconds from 1970-01-01T00:00:00Z UTC until the specified UTC date/time, ignoring leap seconds. This is equivalent to the IEEE Std 1003.1, 2013 Edition [POSIX.1] definition "Seconds Since the Epoch", in which each day is accounted for by exactly 86400 seconds, other than that non-integer values can be represented. See RFC 3339 [RFC3339] for details regarding date/times in general and UTC in particular.
