Many of us thought Twitter was content to watch its Mac app die a slow and painful death, as the company hasn’t updated the app in forever, but new life has been breathed into the app at last.

Twitter just announced an update for the Twitter Mac app that brings Retina display support, better photo sharing, and support for 14 more languages. The app icon also received an update, along with the tweet composer, in what is the first update in nearly two years.

Here’s Twitter’s list of updates: 

I like to keep my iPhone’s lockscreen clean and free of distractions. Jailbreak tweaks that add weather, RSS, and more are useful for many, but the lockscreen can easily start to feel cluttered after awhile.

That’s why I’m excited to present “atom,” a new jailbreak tweak for the lockscreen that replaces the unlock slider with a beautifully subtle app launcher.

Slugline is a new app for screenwriters from Stu Maschwitz (movie maker, visual effects superstar and guy named Stu). It’s a Fountain-based app for writing movies and outputting them in industry-standard Final Draft format, but in use it’s more like a simple plain-text Markdown editor.

LinkedIn has rolled out new apps for Android and iOS that boast brand new designs, faster navigation, and new features. Users will now find an increased focus on their news stream, with conversations, network updates, and more now front and center. The update even comes with a fancy new demonstration video; check it out below.

My favorite read-later app, Pocket, has revamped its sharing options to make it way easier to send articles and snippets to other people. It’s powered by email, although once you’ve set it up you wouldn’t know it. And yes, for those who have been following along, it totally lets you save your favorite passages as highlights, although you’ll need to hack things to get that working.

Grabby, a new tweak from esteemed jailbreak developer Ryan Petrich, allows you to quickly launch your most frequently used apps from your iPhone’s lock screen by extending the functionality of the built-in camera slider. Find out more about how it works and where to download it below.

LaunchBar power-users should get their virtual asses over to developer Obdev’s nightly builds page and grab the latest version of v5.5. Amongst a whole bunch of neat fixes and tweaks it adds one essential new feature: support for your iCloud documents.

Ulysses 3 is a superstar text editor which takes a whole new approach to, well, to editing text. I love it – it’s my favorite new piece of software in a long time – but there are one or two gotchas which could stop me using it full-time to write posts for the web.

Mozilla has released Firefox 20 for Mac users, and this major update brings several new features and improvements to the web browser. Two of the biggest features are “per-window” private browsing and a redesigned download manager.

You can now open a private browsing tab instead of having to open an entirely new window and close the current session. The new, Safari-like download manager is a little arrow that sits in the browser’s toolbar next to search. You can click it to see and interact with all current downloads.

Here’s a little something that might get you formatted-text nerds excited: Rich Notes, yet another new text-editing app, lets you write on the iPad in rich text. That is, you can italicize and embolden your words right there on the page. Yes, this works with some other apps, but Rich Notes lets you use keyboard shortcuts to do it. If you have an external keyboard hooked up, CMD-B and CMD-I will do just what they do in every desktop app.

Rich notes comes from the developer DenVog, who also makes the excellent Index Card app for iPhone and iPad. It’s due to launch on February 20th. Let’s take a look:
