Have multiple search result windows at the same time. Constrain search to just preselected parts of your document. See the structure and depth of your documents in the line number and folding ribbon. Fold text away based on depths or however, you want. Select lines and/or depth easily with a single click. Select to matching braces by a simple double click.

A drop-in replacement for UILabel that supports attributes, data detectors, links, and more. TTTAttributedLabel provides a simple way to performantly render attributed strings. As a bonus, it also supports link embedding, both automatically with NSTextCheckingTypes and manually by specifying a range for a URL, address, phone number, event, or transit information. It also includes advanced paragraph style properties. As of version 1.10.0, TTTAttributedLabel supports VoiceOver through the UIAccessibilityElement protocol. Each link can be individually selected, with an accessibilityLabel equal to its string value, and a corresponding accessibilityValue for URL, phone number, and date links. Developers who wish to change this behavior or provide custom values should create a subclass and override accessibilityElements. TTTAttributedLabel can display both plain and attributed text: just pass an NSString or NSAttributedString to the setText: setter.
