[REQ] Menu items for customizable width and justification

[kiranwayne]

Thank you for this awesome script!

Would it be possible to add two new menu items for the following?

1. customize the text width on each website - could be named "Set Custom max-width" (which defaults to the current 100%) or have one menu option each for chatgpt, perplexity, and poe
2. be able to justify text - could be named "Enable/Disable justification"

I've made my own modifications in lines 760 through 773 in version 2025.4.21.2, where I set the chatgpt max_width to 80% and perplexity max_width to 60% as that works best with my monitor, ensuring readability while being wider than the defaults without the script.

        widescreen() {
            widescreenStyle.innerText = (
                env.site == 'chatgpt' ?
                   `.text-base { max-width: 80% !important } /* widen outer container */
                    .tableContainer { min-width: 100% }` // widen tables
                : env.site == 'perplexity' ?
                   `.max-w-threadWidth, .max-w-threadContentWidth { /* widen limiting Page/Answer containers */
                        max-width: 60% }
                    @media (min-width: 769px) { .col-span-8 { width: 151% }} /* widen inner-left container */
                    .col-span-4:has([class*=sticky]) { display: none }` // hide right-bar
                : env.site == 'poe' ?
                   `[class*=ChatMessagesView] { width: 100% !important } /* widen outer container */
                    [class^=Message] { max-width: 100% !important }` // widen speech bubbles
              : '' )

With Gemini 2.5 Pro doing most of the work, I've prepared a similar script for Deepseek that I use personally. Please find attached the script and a word document with the images demonstrating how it looks and works in practice.

Attached are a couple of scripts with just the two requested features. Again, most of the work has been done by Gemini 2.5 Pro, with your original script as reference.

Hey what are the images you refer to?

[adamlui]

I see in the DOCX you attached some imgs, I know what you're asking for though because someone asked for a slider before so I'll just work on that, for justification could you expand on that though

for DeepSeek I can't add it because Google has a terrible policy where they disable the extension for every user if new site matches are added so they can re-accept new permission and I'm unwilling to sacrifice all my hard earned users when it shoould be reward instead to support a whole new domain (but I will create a new DeepSeek extension when I have time)

[kiranwayne]

Deepseek:
Thank you for explaining the situation with Deepseek. I understand your position and wasn't suggesting you add it to your script - just using it as an example of the kind of features I had in mind.

Slider:
A slider would be very helpful and user-friendly for both technical and non-technical users. I appreciate you considering this feature.

Justification:
By "justification," I meant having the text align so that both the left and right edges are straight (i.e., applying text-align: justify !important;). Right now, the right edge of the text is uneven by default.

Thanks again for your work!

[adamlui]

For the justification can you show a screenshot? Re: slider actually I spent hours today and designed a beautiful one that worked so smoothly, then buggy GitHub Desktop tricked me into thinking it got saved into a branch but instead all the code got deleted :( but I will resume it tomorrow after I make some more updates like grouping toggles into categories that I've been meaning to do anyway, then when I add new ones like "Widescreen" and "Full-Window" (i.e. same as chatbar buttons) the menu won't be so long (also required to make sense with slider since Widesccreen will not always be on so sliding with no effect will be confusing without hte toggle)

[kiranwayne]

Sorry to hear about the issue with Github Desktop. Please see images below for the justification issue.

Hey @kiranwayne both features are now available in v2025.8.4+

[adamlui]

Sorry I forgot you're using the userscript, only Justify Text is added to that, for the slider I have to make new component

[adamlui]

I understand that the purpose of ChatGPT Enchanted is to adjust the overall width of the interaction panel relative to the screen.

I just tested it again it still doesn't do anything for me...

In contrast, your script modifies the width of the response container within that interaction panel. It seems to me that your script sets the interaction panel to occupy too large a portion of the screen by default.

I still didn't understand the issue can you please share a screenshot?

[adamlui]

Check it out here's how it's supposed to work:

If yours doesn't work like this, can you post a screenshot of what the sliders/toggle states are when it didn't work?

[ahnupeng]

Dragging the scrollbar cannot accurately locate the desired value. Can text box be added to allow directly entering the width value?

[adamlui]

Text box would add complexity, what happens if you click the middle of the bar for example?

@ahnupeng I added your request:

Is it to your satisfaction?
