How to put more than five apps in your Samsung Galaxy S5 Toolbox without root
What Toolbox does in a nutshell is host a drop-down list of shortcuts for five of your most used apps. The little dotted circle can be freely moved around the display so that it doesn't get in the way of your current app layout, too, and yet gives you quick access to your oft-utilized applications anywhere you are in the interface or apps with a single tap.
How about if you want to have more than five apps listed there, or, better yet, swap between categorized app collections? Fret not, as the solution to that comes in the form of a simple app, and it doesn't even require your Galaxy S5 to be rooted. Here's what to do:
2. You will now be able to add much more than the default five apps in the Samsung Toolbox drop down list, and choose to run them from anywhere in the interface. Be careful, though, as at the S5's screen dpi, you can't add more than 12 apps without garbling up the works, but that number should be plenty.
3. If you want to have categorized Toolbox lists with many apps each, and swap between them on the fly, you can install the S5 Toolbox Addon app directly from the Play Store, donating $1.51 for the developer's efforts, and this is all that's required.
