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

That script sounds like it'd be very useful!
Can it be edited in any text editor or is it somehow compiled already?

If it's editable I think I could probably figure out how to tweak it
to do exactly what I want.

Can you link to the file or text?
I've never implemented a script within photoshop though
I've used them in indesign.

Personally I still use a Flash Panel to trigger Scripts that automatically save the active file as is or separated (according to a couple of print conditions) psd or tif to a Links-folder it it exists, beside the original if no such folder is present.
But a Script could achieve something similar, in this example hitting enter will raise the folder selection dialog and there are four buttons hitting one of which will close the dialog and save jpg-copies with certain quality settings, respectively a flattened tiff copy without alpha channels or as a layered tiff. (No option for additional settings, though.)
Would that be of use to you?

I'll give those links a try, cheers. I think the best way to explain what I'd like is my "in a perfect world" scenario.

The usual file --> save as dialogue would only have 3 formats: JPG, 16-bit TIF, and PNG only. I've gotten into photography and still end up with JPG as my final output for for all shots that don't require printing, and 16 bit TIFFs for files that will be printed and have more dynamic range than an 8 bit format can hold. I use PNG for web images that have transparency.

I don't mind dealing with the usual secondary dialogues that come up after I choose a format (like JPG's quality slider, TIF's compression format, etc.)
I usually can just press enter and accept the defaults or last-used setting.

In a less perfect world, there's still a big list of formats, 90% of which I never use, but those 3 popular formats are at the very top of the list.

In an even less perfect world, I'd have 3 separate keyboard shortcuts to save files, one for each of the 3 formats. I'm not sure if that can be recorded as a photoshop action... I don't think it prompts me for a save location, and I'm not sure if it can prompt me to tweak those other dialogues like the JPEG quality slider.

There are at least two Photoshop Scripting Fora

where you could ask for help, at ps-scripts.com there is also a section for professional scripting services:

But what exactly is your minimal requirement to constitute an improvement over the current situation?
How many file formats do you regularly use, which settings do you use regularly (like with jpg – do you really use all 12 quality settings or just one or two of them), would a Script for each format suffice, ...?

I'd be willing to try it but I can't seem to find a script that does this via google. I don't know how to write one myself... Do you know of one? Or where I might ask to commission one?

A Scripting approach may not offer exactly all of what you are after but I suspect it could (possibly in conjunction with an html5 Panel) offer some improvement.

I used to run a clunky 3rd party app called "Formats Customizer", except it is constantly flagged by my antivirus program (and my browser also blocks attempts to download the installer). It may actually have adware, I dunno if it's a false positive or not. I got sick of the warnings so I uninstalled it. If there's another solution, I'm not aware of it.

Over three years ago I posted:
»But in the meantime you could look into a Scripting solution for your personally-most-popular formats.«
So what have you done to streamline your saving process so far?

I wrote the original post over 3 years ago and I still want this feature.

We're all so used to it that nobody even thinks of streamlining it.
But imagine if, in order to say OK a dialogue box, you couldn't just hit enter,
you had to hit O, the down arrow twice, then enter. For every single
dialogue, every single time, year after year.
Thousands of needless keypresses and clicks.

That's what it's like saving a file in photoshop.

Chris,
Please find a way!
