P: Ability to arrange & customize save-as file formats so popular formats are at the top

It's done, but the way they have their page set up, only they can post on the page. You need to look under "Visitor Posts". I also sent them a DM with the same info, but you won't be able to see that. Sent them the same one in 2018, never got an acknowledgement...

Do it!

Do it! This is just a pathetic oversight and laziness on adobes part.

Time for us all to pile onto the Photoshop Facebook page and let them know our displeasure. I'm happy to start it off, but it needs everyone not just to like the post, but add a "Me too!" comment.

I would also like this fixed. Just something simple. Like picture or video. Meme. 

I'm probably in this thread somewhere. I've posted on a variety of threads and initiated new threads about this issue for years. WHY does Adobe insist they would only respond to this if there was a vocal outcry from their users? How many UI changes have they made that NONE OF US asked for?
Since when is UI development user driven and democratic? What an idiotic position for Adobe to take.

This is simply an area of the UI that needs an upgrade, should not be dependent on user requests.
The save dialog box is clearly a friction point in a user's workflow. That file types are not easily arranged, or deprecated means that every SAVE requires more attention, clicks from the user.

Some file types I will never use, such as those for medical imaging. But those users who DO need those should be able to structure easy access.
Who in the world uses Scitex CT anymore? Targa? .IFF? EPS? DCS? In the Mesolithic I used DCS for spot color and 2 color duotones. Brilliant, but not needed in today's workflow.

So if it is user input Adobe wants in order to determine need then Adobe should have some sort of easy to use survey page. Not expect that a user will become so damn irritated that they will spend half an hour trying to find the correct venue to express their thoughts.

If there was a survey page that I could direct colleagues to, there are 45 users in my work group who would vote for this in a minute. But our priority is working, not trying to educate Adobe on an issue that has been brought to their attention for over 10 years, over and over.

This is a no brainer fix.

Think of it as classic hi-tech company nincompoopery. Any real programmer knows this is a couple hours of work and would allocate a week, to allow time to sneak in more indecipherable icons to spring up with nor request for them. The larger job is documentation. That may actually take a week to do. Obviously, after all these years, they are simply being jerks. You can suck up to them if they stick their nose in to see what's on this board now and then, but that doesn't work - how many years of it do you need to see? This is not a prioritize according to votes project because a. any user of PS deals with this ridiculousness, and 2. this is not a big job. The only "project" involved is coordinating with Documentation. You Adobe people should be ashamed.  That you are not is telling.

Such a simple thing- already you can customize dialogs in drop down menus: why not this one you use on every image???

I'm a me too!  Tired of 'just living with it'.

Photoshop 2020 is released, and still no way to customize the Save As dialog... Maybe the developers were too busy adding brand new exciting Photoshop bugs!
