Круто всё нравиться !!!
nice....
Something seems to be broke with the latest version of Chrome. I can't edit CSS or view settings.
Got LOVE <3 for this toolbar...its very practical and efficient in every way possible, I give this toolbar the highest recommendation possible from me to any front end Dev or to be fair any coder out there creating work for the visual end type projects/work, A credit to the creators of this toolbar, there are numerous amounts of things it can do rather than the usual free tools cant do we all are use to, The past dictates anything free is usual trash or full of spam however this actually does not follow the normal pattern we all hate to see. So again a big plus plus rating from me, thank you to the dev/s for this handy piece of kit i use it every single day without fail cheers :)
so much helpful
nice tool
Awesome :)
What a helpful tool :)
برنامه ای بسیار خوب که بدون شک هر طراحی با آن آشنایی دارد
