Short:
Helps you to copy labels in any Github repository into one of yours.
Long:
This is helpful when you create a new repo on Github. When you create your labels in one of your repos you probably get used to them and would want them in your brand new repo as well. Ths website avoids the burden of manualy creating labels on Github.
You don't have to copy labels from some repo, you can just add/remove/edit your repo's labels via here, and commit all the changes at once.
Usage
- List your repo's current label
- Copy (append) some other repos' labels into your current labels (optional)
- Edit the labels list as you wish
- Commit your changes
Yes, not really much different from Github itself. But
the thing is you can do those as bunches here. The main thing is that you can also copy another repos's labels into yours with or without some modifications.
