As a web developer, this is crucial to my work.
The Chrome version has been wacky lately. Not sure if it's because of Chrome or WD. However, this tool is amazing. I'd be lost without it as I'm sure many others would be too. There are several things not working properly for me. Reload and Layouts. They just don't work at all. I see others are experiencing it too but no one has a fix from what I can tell.
Great tool. love it
Оч нравилось расширение пока не перестало работать, не знаю что делать =\
I use this every day. Would be lost without it.
хорошо, мне нравиться, и очень удобно встало, занимает мало места.
great extention ! love it !
Has some neat features made simple for those that aren't experts
the tool is great! but couple of things i noticed to make it the best. 1) the size of the popup when u click the tool is smaller than it should be. 2) i would love to be able to add more custom fields for form population. Thanks
i love it in FF i love it in GC !!!
