How to use term edit page instead of view page?
There are a few ways we could achieve this:

Option 1: Introduce a route subscriber in a custom module with below code:


    $route = $collection-&gt;get('entity.taxonomy_term.edit_form');
    $collection-&gt;add('entity.taxonomy_term.canonical', $route);


This code would replace the edit_form to the canonical route. 

Note: Might need to update the local task to remove the view tab as it is confusing to see the edit form in the view tab (as below). 



Option 2: Extend Drupal\taxonomy\Form\OverviewTerms form and overwrite buildForm method and use $term-&gt;toUrl('edit-form') as below:

      $form['terms'][$key]['term'] = [
        '#prefix' =&gt; !empty($indentation) ? $this-&gt;renderer-&gt;render($indentation) : '',
        '#type' =&gt; 'link',
        '#title' =&gt; $term-&gt;getName(),
        '#url' =&gt; $term-&gt;toUrl('edit-form'),
      ];



However, it might not be a good idea considering how complex buildForm method is and the effort to keep up with any core changes.
