Topbar+ is a lightweight application that expands upon Roblox’s topbar to give you greater control and customisability.
- Add and remove topbar icons with ease
- Customise the design of your icons with themes
- Enhance the default toggle behaviour
- Easily configure toggle menus for your icons
- Prompt notifications
Basic Example
local icon = iconController:createIcon("Shop", 4882429582, 2)
icon:setToggleMenu(gui.Shop)
icon:notify()
Themes
By default, Topbar+ mimics the standard Roblox topbar. Themes provide you with the ability to enhance the design and behaviour of this. For details on creating and applying themes, visit the documentation.
‘Soft blue’

Say hello to v3.0.0! 
A design overhaul to match the new topbar…
Icons, captions, dropdowns, menus… everything! v3 aims to mirror the topbar so you can seamlessly build upon it.
…but with inbuilt support for the old topbar
Not all clients see the new topbar… yet. v3 solves this by listening for differences and adapting to a classic design accordingly.
A complete codebase rewrite and re-organization
Readability and performance have been the driving reasons behind this. By outsourcing logic to UIComponents and reorganizing instances into more appropriate containers the Icon and IconController have collectively shrunk from >3000 lines of code to ~1000.
An easier system to modify icon appearance and behavior
You’re no longer limited to predefined settings… you can modify… anything! 
The way you modify icons has also changed to be more straightforward. More info on that here.
TopbarPlus is now a package
No more faff when updating… just right-click the package, update and bam, all set! 
More details here.
TopbarPlus now supports Wally
You can find that here!
Improved support for gamepads and mobile devices
Pretty much the title, lots of small improvements to make navigating icons on different devices that much easier.
Overflow upgrade
Overflows now become horizontal menus instead of vertical dropdowns. More about that here.
Brand new documentation
Happy reading! You can find the v3 documentation here.
MIT → Mozilla Public License v2.0
You can use TopbarPlus free of charge. All you need to do is provide credit back to this resource (such as link to its devforum post) and to open source any significant changes you make to the package.
Backwards compatibility with the majority of methods from v2
The majority of v2 methods and features have been built into v3 to make for an easy transition.
Changes since v2.9.1
