[Feature request] Remember "Lock" settings for each note file

No

Describe your feature request!

In the current version 2.5.1-rc.2, all lock settings are toggled off when the file is closed and opened again. The screenshot below shows the "Lock" settings of a file.

My feature request: When a note is opened and the lock settings are changed (e.g. Lock Zoom, Lock Horizontal, Lock Vertical, Lock Layer), the state of those options should be saved so that when that note is opened again, the Lock settings persist.

Given that it some users might want Butterfly to remember lock settings, while others users might not want this feature. I believe that having a toggle button in "Settings" with the name "Remember Lock settings" would be more convenient for most users.

Do you want it globally or document dependent?
If document dependent, then maybe also save the current page and the position?

The problem on document dependent is, I'm not sure how I want to do it. I'm thinking about having always an extra file that saves this (for example if you have a document.bfly, there might be a document.bfly.state besides it).

@CodeDoctorDE

Do you want it globally or document dependent?

In my use case it would be more convenient if the Lock settings were document dependent. That is, the app should store different values for "Lock" settings for each note. Those "Lock" settings would be automatically stored by the app whenever any of those options change while editing a note.

If document dependent, then maybe also save the current page and the position?

I was just going to create another feature request regarding this topic. Storing the page, the position and the zoom level of the last modification would be a time-saver for some users. This way, when the user opens that note again and is taken to the part of the page where she/he was, the user will remember what she/he was doing the last time she/he visited that file.

The problem on document dependent is, I'm not sure how I want to do it. I'm thinking about having always an extra file that saves this (for example if you have a document.bfly, there might be a document.bfly.state besides it).

I am not very familiar to Android development and the source code of this app, so I can't give any advice on the best way to store this information considering the current code base.

I just decompressed a *.bfly file in one of my Butterfly backups and I noticed that each note has a directory called BFLY which contain a file called info.json. Perhaps, another option would be to add it to that file. The code block below shows my idea to store the "Lock" settings and the current page and the position in the file info.json..

$ cat ~/Downloads/butterfly-backup-zip-decompressed/Documents/my-document-1/BFLY/info.json
{
    "tools": [
        (... omitted lines ...)
    ],
    "exportPresets": [],
    "view": {},
    "extra": {}
    "lock": [
        {"key": "collection", "value": true},
        {"key": "layer", "value": true},
        {"key": "zoom", "value": false},
        {"key": "horizontal", "value": true},
        {"key": "vertical", "value": true}
    ],
    "lastModification" {
        "date": "2026-04-26T20:51:43-0500",
        "page": {
            "index": 2,
            "title": "Boolean Algebra"
        }
        "position": {"x": 482, "y": 590}
        "zoom": 300
    }
}

Im thinking about having an extra menu button in the lock menu to save this current lock setting in the document so you can also change it temporary.

The position and zoom needs another ocncept since you can use the origin waypoint to set the initial view

Or how about long press to lock the option permenantly.

That would be a really good idea, then I can show it by the text being italic
