After being in development for six months, GNOME 3.24 was released today, bringing improvements such as Night Light, weather information in the date / time indicator, along with updates to its applications, and more.

Update: this issue was fixed (thanks Martin), although you may still encounter it in other applications.

The Dropbox indicator is broken in Ubuntu 17.04 Zesty Zapus (currently in beta): the menu doesn't work and Dropbox uses a different icon, probably because it tries to use the tray instead of the indicator.

Streamlink Twitch GUI (previously Livestreamer Twitch GUI) is a multi-platform Twitch.tv browser.

The application is powered by Node.js, Chromium and Streamlink, though it can still use Livestreamer (which is no longer maintained) too.

For those not familiar with Rclone, this is a cross-platform command line tool for synchronizing files and folders to multiple cloud storages, which supports Dropbox, Google Drive, Amazon S3, Amazon Drive, Microsoft One Drive, Yandex Disk, and more.

My downloads folder is pretty messy but I can't just delete things because I still need most of the stuff I download. To "fix" this, I was looking for an app that can automatically organize my downloads, and I stumbled upon Classifier, an easy to use command line tool that can organize files in any directory.

Here's an example - on the left there's a folder which contains various file types (images, archives, documents, etc.) and on the right it's a folder that contains the exact same files as the folder on the left, but after running Classifier to organize it (into folders):

An alternative to KDE Connect is Pushbullet. While the free version has some limitations and it doesn't offer all the features available with KDE Connect, it does provide options to send files up to 25MB, send messages from your desktop (limited to 100/month in the free version, and a storage cap of 2GB) and most importantly, it can mirror your phone's notifications on the desktop.

Note that Pushbullet requires both the Android device and desktop to be connected to the Internet, but they don't have to be in the same network.

Todo Indicator is an AppIndicator to for todo.txt-style todo lists. The indicator displays the list of tasks from a todo.txt file and lets you mark tasks as done directly from the indicator.

The original Todo Indicator was last updated back in May, 2014, so WebUpd8 reader William decided to fork it and add a new feature: filtering based on a specific context or project. Furthermore, indicator was updated to work with either Python 2 or Python 3.

If you use VirtualBox 5.1.x with a GNOME desktop (GNOME Shell, Unity and possibly other GTK-based desktops as well), you may have noticed that there are some focus-related issues:

Meteo Qt is a tray application that displays the current weather temperature on the panel, with a 6-day forecast easily accessible from its menu. 

Meteo Qt in Kubuntu 17.04

The application is based on Python 3 and Qt 5, and while it is aimed at Qt-based desktops (like KDE Plasma or LXQt), it works pretty well on GTK-based desktops as well (either as a tray or as an AppIndicator).

While the last stable mtPaint version was released back in 2011, there have been quite a few development releases since then, with the last one dating to June, 2016. I couldn't find a PPA with the latest mtPaint 3.50 development releases, so I created one to make it easy to install in Ubuntu and Linux Mint.

Oomox is a tool that allows generating color variations of the popular Numix GTK2 / GTK3 theme, as well as icons to match them.

The application comes with a large number of built-in presets that can be further customized, and it supports GNOME, Unity, Xfce4 and Openbox.

The minimum GTK3 version required to use it is 3.18 (so it supports Ubuntu 16.04 and newer). The themes might work with older GTK3 versions, but you may encounter issues.

Oomox already had Unity support, but with the latest 1.2.0 version, themes generated with it now have the correct window buttons color instead of the default Numix color:

Uber CLI is a tool to get time-to-pickup and price estimates for Uber from the command line. The application cannot be used to request Uber rides.

This is useful if you use Uber and the command line a lot, as it's much faster than checking these details on your phone, especially if you create some Bash aliases for your home address and the places you frequently use Uber to get to.

The new Skype for Linux app was released as an alpha version back in July, and it included support support for one-to-one and group voice calls, but no video call support. Video call support was added back in October, but only between Skype for Linux Alpha clients

This changes with the latest Skype 5.0 for Linux, which was promoted from Alpha to Beta. The latest version adds support for one-to-one video calls with Skype for Android, iOS, Windows, and Mac.
