>designers should learn to code
Agreed, professional designers should…..casual users probably not so much.
We don’t know the target market for this product (and Adobe’s) but I suspect that “we the professionals (or seriously interested amateurs)” aren’t it.
I think it’s worth remembering that Adobe’s Edge offerings (I think that’s the collective term) are experimental so they can see how well they operate on their own and each other so they can, perhaps, bundle them all into a single product.
Then again, as I suggested, they may finalise them and release them individually.
If Adobe decided to sell Brackets at a similar price as Sublime Text, I think ST could see some serious competition.
