Portable Taskbar++

Designed as the portable edition of Taskbar++, Portable Taskbar++ is an application that enables you to customize the buttons displayed in your Windows taskbar using basic drag-and-drop operations.
It features advanced, yet approachable options that make the tool accessible to all types of users looking to personalize their operating systems, even casual users.
Before proceeding any further, you should know that this software product hasn't received updates for a long time and doesn't run on newer Windows editions.

Portability advantages

Since there is no setup pack involved, you can drop the downloaded app files in any part of the HDD and just double-click the executable to launch the program on any computer with minimum effort and no previous installation. There's also the option to copy Portable Taskbar++ to a USB flash drive to directly run it on any PC. It shouldn't make any changes in the Windows registry.

Simple GUI for customizing taskbar options

The main configuration panel has a simple appearance that doesn't put emphasis on graphical elements, but it's easy to navigate. You can create a list with the full paths of applications in order to suspend Taskbar++'s activity during their runtime, play sound at the sort mode's beginning and end, disable smooth animations when dragging the taskbar buttons, and show the tooltips on the taskbar buttons.
Moreover, it's possible to modify the text color of taskbar buttons and the background color (under XP visual style), as well as set the icon's and text's position by fine-tuning the X and Y coordinates.
You can switch to another UI language, hide the app's icon from the systray, check for the latest edition at startup automatically, apply a proxy configuration for connecting to the Internet, and study logs with any errors and other details about the program's activity.

Conclusion

Portable Taskbar++ features handy options for configuring some taskbar settings. Too bad it doesn't support newer Windows editions.
