@baris That's it!
That was the problem, I changes the directory layout to something more familiar to me.
To test the solution I created a directory 'public' and saved a 'tmp.js' to it. I started grunt, changed the file and it recognized the change.
Thanks for your help!

If you have access to the plugin directory I assume you could do the follow:

1. Go into directory nodebb-plugin-contact-page/languages/
2. Make a copy of the directory en-GB and name it he
3. Go into the new directory he and open file contactpage.json
4. Change english texts on the right to the corresponding hebrew texts and save.
5. You may need to rebuild and restart nodebb.

I don't see any other way to change it, but if you can't make these changes then you'll likely need to request them from the plugin developer.

For 'Tail hiding' add the following custom CSS:

.pagination-block {
    display: none;
}

@julian Wow, thanks for the fast reply!
It is a plugin of my own design. Grunt doesn't seem to detect any file changes; templates, JS files, nothing. However when I build first, then start the server (either by NodeBB start or grunt) the plugin works according to my changes.
As a test, I have made small changes to NodeBB core files and grunt detected those changes. I am just wondering if there is a problem with having my plugin attached via a symlink, maybe??

Should grunt watch for file changes to a plugin attched by a symlink? It doesn't seem to be working for me.
