@michaelbukachi Could we use one of these for our drag and drop icon, which do you prefer given the screen real estate? Also, do you think it should be on the right side?
https://fontawesome.com/v6.0/icons/grip-vertical?s=solid https://fontawesome.com/v6.0/icons/grip-lines?s=solid

With this, we'd have to introduce fontawesome into hakawati. But it seems we don't have an alternative.

@michaelbukachi Ok, let's skip fontawesome for now.

Do you think we could use el-icon-minus and stack 2 of them on top of each other? And if it doesnt look good, you can just add one as a placeholder until we find another one in element 😅

@michaelbukachi On second thought, let's get this PR merged and I'll ticket the icon in a separate enhancement for the future. Maybe we'll find a better icon to use by then 🙆‍♂️
