Hello,
You probably do not need a plugin if you use built-in function of PluXml:

here is an example to insert in article.php (article-x.php) templates where you want it to appear. It will only show links to article of same category.

<ul>
    <?php $plxShow->lastArtList('<li><a href="#art_url" title="#art_title">#art_title</a></li>',4, substr($plxShow->artCatIds(), 0, 3)) ?>
</ul>

Here is the list of the functions that template files can use : https://wiki.pluxml.org/docs/develop/plxshow.html

The plugin you look for might be https://ressources.pluxopolis.net/banque-plugins/plugins/SuggestAvecImage.zip (fr/en languages included)

gcyrillus-nomade, respect!
Great, your code works, I added the date of the article:

        <?php $plxShow->lastArtList('#num_day #month #num_year(4). #art_title',4, substr($plxShow->artCatIds(), 0, 3)) ?>

$plxShow->artCatIds() returns a comma separated list of category ids.
But $plxShow->lastArtList() expects a vertical bar ( | ) separated list as the 3rd parameter.
So here is a better way if an article is owned by several categories :

<?php
$template = '#num_day #month #num_year(4). #art_title';
$maxItems = 4;
$catList = str_replace(',', '|', $plxShow->artCatIds());
$sortBy = 'rsort'; # may be 'random' or 'alpha'
$plxShow->lastArtList($template, $maxItems, $catList, '', $sortBy);
?>

To add a few more infos, you might also want to exclude the current article from the list:

<?php 
    // backup the whole list of articles
    $plxGlob_arts_aFiles = $plxShow->plxMotor->plxGlob_arts->aFiles;

    // get current article id
    $currentArtNumber =  $plxShow->plxMotor->plxRecord_arts->f('numero');

    // get cat id(s)
    $currentArtCatId  = substr($plxShow->artCatIds(), 0, 3); // only the first one
    $currentArtCatIds = str_replace(',', '|', $plxShow->artCatIds()); // all of them 

    // remove current article from the list
    unset($plxShow->plxMotor->plxGlob_arts->aFiles[$currentArtNumber]);

    // extract & print article datas  from selected catId(s)
    $plxShow->lastArtList('#num_day #month #num_year(4). #art_title',4, $currentArtCatIds ) ;   

    // restore the whole list
    $plxShow->plxMotor->plxGlob_arts->aFiles = $plxGlob_arts_aFiles;
?>

@bazooka07 je crois qu'il y a une typo dans https://wiki.pluxml.org/docs/develop/plxshow.html#artcatid (manque le s ou bien cette fonction à été renommée depuis ?)

edit, and the long version restoring the article number and its data (also for infos)

                        <?php 

                        //backup current article article from $plxShow->plxMotor->plxGlob_arts->aFiles
                        $currentArtNumber =  $plxShow->plxMotor->plxRecord_arts->f('numero');
                        $currentArtContent=  $plxShow->plxMotor->plxGlob_arts->aFiles[$plxShow->plxMotor->plxRecord_arts->f('numero')];

                        // get cat id(s))
                        $currentArtCatId  = substr($plxShow->artCatIds(), 0, 3); // only the first one
                        $currentArtCatIds = str_replace(',', '|', $plxShow->artCatIds()); // all of them 

                        // remove current article
                        unset($plxShow->plxMotor->plxGlob_arts->aFiles[$currentArtNumber]);
                        // extract article data  and select catId(s)
                        $plxShow->lastArtList('#num_day #month #num_year(4). #art_title',4, $currentArtCatIds ) ;       

                        // restore removed current article in $plxShow->plxMotor->plxGlob_arts->aFiles for next scripts running
                        $plxShow->plxMotor->plxGlob_arts->aFiles[$currentArtNumber] = $currentArtContent;
                        ?>
