Limit the number of lines of text that appear in your designs.
Select one or more blocks of text, set the number lines you need, then just click apply.
If you select text that is part of a component or instance you can choose to apply it to the selection only or apply across all the instances to keep them consistent.
If you need the original text back just press reset and your original text will reappear.
Hopefully this plugin will become redundant in the near future but in the meantime you can save yourself a bit of time.
