I can't use it because it's too lag.
I absolutely love this tool, but there's one thing that bothers me a lot: at least in opera, where im using, a lot of times some distance measurements get behind the rulers. I'd love a shortcut for hiding the rulers or if the measures could be above it (with a clear readability). But thanks for the tool anyway :)
Amazing work! Not giving good results on mobile and phone. Is there any option for that?
Para quem precisar alinhar e calcular espaçamentos esta a melhor ferramenta que usei para o chrome.
Excelente ferramenta para designer!
really nice tools
Really good at free tier. Found a bug I think: setting the ruler width to 0 converts it into a big grey square and makes the settings inaccessible... so I had to re-install to fix that. Side-note/request: if it doesn't already exist, a toggle for hiding the ruler would be nice.
Awesome extension for web design and precise measurements of elements on the screen.
One of the most awesome ever made extension. Thank you!
Amazing! Replaces several other extensions.
