(Reuters) - Twitter Inc on Thursday said it will roll out a new subscription product initially in Australia and Canada called Twitter Blue, which will let paying users edit their tweets before posting and change the color theme of their app.

Details of the feature were first uncovered last month by software engineer Jane Manchun Wong, who is well-known in the tech industry for reverse engineering apps and discovering new features before they are officially launched.
