The cncjs-shopfloor-tablet UI has almost exactly what you are asking for

Is it possible to use or add that function to pc cncjs version? i have dedicated laptop for controlling cnc and it runs pc version of cncjs. Dont have there any other devises to use it on machine

Yes you can run cncjs-shopfloor-tablet from the PC app. Do this:

1. Go to https://github.com/cncjs/cncjs-shopfloor-tablet/releases/tag/v2.0.0 and download the release asset file cncjs-shopfloor-tablet-2.0.0.zip
2. Extract that .zip file to some folder on your PC. On my PC, Windows Explorer extracts by default to a subfolder of Downloads, but you can choose any folder.
3. Use a text editor like notepad to edit the file \Users\YOURUSERNAME.cncrc . Add a "mountPoints" section, or if one already exists, add an additional entry to it. The file probably starts with something like this:

{
    "state": {
        "checkForUpdates": true,

You need to add a new section so it looks like this:

{
    "mountPoints": [
        {
            "route": "/tablet",
            "target": "C:/Users/YOURNAME/Downloads/cncjs-shopfloor-tablet-2.0.0/cncjs-shopfloor-tablet-2.0.0"
        }
    ],
    "state": {
        "checkForUpdates": true,

Replace YOURNAME with your own user name - or replace the entire target: path with the location where you extracted the .zip file. Save the modified file.

Then restart the cncjs app and look in the View menu:

If you click on the /tablet item down at the bottom, it should take you to the tablet UI in another browser.

It it doesn't work, you probably did not follow the instructions precisely. The syntax of the .cncrc file is very picky so you must get all the braces, brackets, comma, and quotes just as shown.
