Here only 50 blocks are displaying in
admin>structure>features>create Components. We want to increase that limit to 100. Please find the attached snapshot.
There are a couple of things you could do for increasing the limit on blocks that you can add to your site. For instance, have you tried increasing max_input_vars limit in your .htaccess or in your php.ini file? From 1000 to, let's say, 2000?
Or increasing your limit in your settings.php file if not?
See if this post here (its second half rather) can be of any help: https://www.optasy.com/blog/how-add-more-lot-more-blocks-your-drupal-site
