When it comes to Twitter tweaks, the focus in the last several months seems to have been more on working on ways to make its platform less prone to being abused by people who use it to spread false and misleading information and harassment, and generally weaponise it for aims that are ultimately harmful. But a recent test points to how the company is also working on other ways of improving interactions and engagement.

Twitter appears to be currently testing reactions in Tweets, which would expand the hearts you already have on there to a range of other options. In the test, first uncovered by social app sleuth Jane Wong, Twitter is testing letting users respond with an emoji of their choice (similar to the pop-up it has for emojis when you compose a Tweet today); or a few pre-selected ones, including “100” (for agreement), a red circle with a line through it (for disagreement), a heart, a crying with laughter emoji, a shocked face, and a pair of pressed palms (for please, yes, let it be so, etc.).
