Ado$e crippled Dreamweaver years ago and have essentially turned it into abandonware unfortunately. Minuscule maintenance mode for 5 years, what’s baked in is aging rapidly or grossly outdated.
Regarding Project VII, sadly it all came quickly crashing down (as you know) when co-founder Al Sparber died in June of 2019, they went on for a while but lost traction quickly until they closed.
Some feel Wappler from DMXzone is the successor to Dreamweaver, that’s perhaps subjective person to person. Pinegrow is another Dreamweaver alternative, again subjective to each individual. With the later you may be able to open your projects and make edits certainly via code or visually in many areas.
If you own Blocs and have all the updates, please spend adequate time getting to know the workflow and come to your own decision regarding if it will meet your personal and professional requirements or not. You can list and post your “must have requirements / features” and someone can express if Blocs can fulfill those, or in what manner you can approach them within Blocs (inbuilt features, add-ons, code, etc.,).
In the end your personal requirements are the essential factor. Can you accomplish and achieve what you and your clients need. Whereas advantages, disadvantages, pros and cons can be subjective from user to user. You need to be clear with yourself pertaining to your own specific needs.
So, give Blocs an earnest go for new sites definitely, but also for rebuilding others also. You should quickly realize how and if Blocs will actually fit into your toolset and needed requirements. How did it go the last time, success ?
