Upgrading to the latest version of the proprietary Nvidia drivers in Ubuntu (or Linux Mint) was pretty complicated a while back. You would either have to use the official Linux installer, which was not always reliable, at least for me, or use a bleeding edge PPA, like the Xorg Edgers PPA, which would upgrade multiple packages, most of which were unstable.

That's no longer the case thanks to the Proprietary GPU Drivers PPA, which offers stable proprietary Nvidia graphics driver updates, without updating other libraries to unstable versions (some libraries may still be updated using this PPA, if they are needed by the drivers, but there's nothing unstable in the PPA).

You're probably familiar with the Unity HUD, or Head-Up Display, which lets you search through and application's menu. Thanks to Rafael Bocquet's i3-hud-menu (and J.A. McNaughton's fork), you can use this menu search feature in pretty much any desktop environment (and in any Linux distribution in which you can install unity-gtk-module).

i3-hud-menu allows searching and navigating through an application's menu using the keyboard, with the use of dmenu (dmenu doesn't have mouse support by default). Here's how it looks like in Xubuntu 16.04:

Oomox is a tool that allows creating different color variations of the popular Numix GTK2/GTK3 theme. It features built-in presets, so you can easily generate various themes without much effort, or you can use the tool to change the theme colors individually.

By default, the GNOME (Shell) overview displays applications in two views: "all", where all the applications are listed in alphabetic order, and "frequent", in which the frequently used applications are displayed.

GNOME Shell supports grouping applications in app folders, and there are two such predefined folders, "Utilities" and "Sundry". Some might not know how to create custom app folders, so here are two ways of achieving this.

Snap packages are not an Ubuntu-only thing any more. Developers from multiple Linux distributions and companies, including Dell, Samsung, the Linux Foundation, and more, announced the collaboration on the snap universal Linux package format, which allows using a single package on any Linux desktop, server, cloud or device.

I recently stumbled on an issue with Dropbox and the Ubuntu flavors that support AppIndicators (except Unity), like Xubuntu and Lubuntu: the Dropbox AppIndicator icon shows up as broken and the menu doesn't work. This isn't a new issue though, and it seems to occur starting with Ubuntu 14.04.

The issue occurs with the Dropbox packages in the official Ubuntu repositories (called "nautilus-dropbox", which doesn't depend on Nautilus and can be used to install Dropbox on any desktop environment) as well as the Dropbox package downloaded from its official website. 

WinUSB is a tool that can be used to create a bootable USB Windows installer from an ISO or a DVD, either using a GUI or from the command line.

The application looks pretty much abandoned, with the latest release dating back to 2013 however, GitHub user slacka forked it, fixed most of its bugs, and updated it to support both wxWidgets 2 and 3.

MATE Desktop 1.14 is now available for Ubuntu MATE 16.04 (Xenial Xerus). According to the release announcement, it took about 2 months to release MATE Desktop 1.14 in a PPA because everything has been well tested, so you shouldn't encounter any issues.

Razer Synapse, the official Razer configuration utility, doesn't work on Linux however, there's a tool called Razercfg that allows configuring some of the Razer mice settings under Linux.
