I hated the Flash Builder name change and found it totally wrong, it turns out some of my reasoning was caused by different understanding of what Flash and Flash Platform means. I've updated my definitions in my previous post, but my concerns about increased confusion are still valid.
If Flash Builder name is indeed to clear up confusion, logical next step is renaming Flash authoring tool, AKA Flash Professional or Flash IDE (or simply Flash before Flash Builder).
Flash is currently a catch-all name, can refer to a SWF file, Flash Player (AKA Flash Platform in marketing talk), the IDE and more. It's comparatively easy to change the authoring tool name.
Other tools by Adobe, that start with 'Adobe Flash', does not end there. Sure, now current usage is becoming 'Flash Professional' but this also creates its own problems (see below) and it sounds like it's part of the version, not the actual product name.
Flash Professional is the premiere tool for creating Flash content. The day it's gone, will be the day sealing certain death for future of Flash. It's more than an animation tool, or a designer tool. It's a complete development tool, which also appeals to designers. Some Flex/Flash Builder users don't get this. I can understand them, they just don't know what Flash Professional is and so they cannot appreciate it.
I think, in all fairness, Flash Professional is still a good name, which needs no change. But Flash Builder users, who think they are the professional users and the Eclipse plug-in is the professional tool, don't like how 'Flash Professional' sounds more 'professional' and above 'Flash Builder'. So, something must be done, sooner or later.
Suggestions coming from Flash Builder users like 'Flash Designer' and 'Flash Animator' are IMHO quite unacceptable. 'Flash Studio' might have been a good name but it's sure to cause more confusion as initial expectation will be that 'Studio' includes 'Builder'.
The new name, should not be unfair to the tool and it should not sound more professional than Flash Builder. It should not be too different from what it is today. Tough job.
But I think I have a good suggestion, something only Adobe can do:
That's it. Everybody knows Photoshop and this name IMHO fits like a glove and has a good vibe. What do you think?
