Screenshot / Code Snippet
About
There's a new tag synonym dashboard, which looks nice except for those thumbs up/down buttons. Since we're Stack Exchange, not Facebook, they should be the familiar triangles instead. I've posted an answer asking for a change; that was status-declined, so this userscript aims to fill the gap.
Download
You can install the script from this direct GitHub link. The source code can be downloaded here; if you want the buttons in horizontal mode, feel free to change it for personal use.
Platform
Developed and tested with ViolentMonkey, Firefox and macOS, but I expect no platform/browser/extension differences.
