yes, tried it
I use quite a few WA Extensions for DW and of course I know the procedure of deleting the site cache.
And yes, they are great and help a lot to make life easier. Thats why we invest quite some money and time into these, even if you could do things on your own, quickly.
I called this Ext. experimental because I never had to uninstall some extensions first and then keep a certain order to re-install them. Maybe its the constellation of my extensions - but even if I un-install it, I get errors from Dreamweaver at every startup. After Dreamweaver loads, I stiil get error messages like missing translators...
There are times (most of the time actually) where you need quick solutions, because our clients want most things done quickly and we want to write bills quickly. Everybody can program forms and validate them. So, if I need more time to get a tool to work than the actual work would take, this is not what I expect.
So, I will use Spry validation and WA's tooltips
