“Why not” isn’t a reason.
It’s not about attachment to the floppy icon. The icon is ubiquitous, by not using it, effort is being expended that could be better spent elsewhere and we risk making Blender less user friendly, or appear so to new users - especially when the icon that is chosen could be confused with icons already employed for other purposes.
It’s just one more thing people need to learn but which brings absolutely no benefit whatsoever.
When making a change - we really should be asking questions like:
- Is there something wrong with the ubiquitous icon, is it unclear or do people not understand it.
- Will the change make Blender easier to use/understand (especially for new users).
- Is it required to fix some fundamental flaw or for performance reasons.
- Is there a valid design or marketing reason for the change.
As far as I can tell - the answer to all of these is no.
Given Blender has come in for some quite heavy criticism in the past over it’s UI, especially prior to v2.5 we really should be bearing this stuff in mind.
There was a poll conducted a day or so back - the consensus from the majority of the community seems to be to keep the floppy icon…surely that’s reason enough not to change it.
