Where to make suggestions?

I’d like to know if there is a proper way to make suggestions for changes in the source code, as I just started using this plugin, because I didn’t feel like making my own.

Just a few quick changes that I would suggest making would be:

In: ../super-socializer/inc/widget.php

Line 27-51:
Add ID’s to the DIV’s and/or use a style sheet, so users can customize the layout.

As there are a few changes that I needed to make instantly just to not co crazy due to my OCD and I’d rather not have the code overridden when there is a plugin update.

Line 42: ( Fix alignment issues and long user name wrapping issues )

Original:

echo "<div style='height:80px;width:180'><div style='width:63px;float:left;'>";

My Change:

echo "<div style='height:60px;width:100%;'><div style='width:63px;float:left;'>";

Line 45-46: ( Make the Name on the Widget Show the Users Display Name not Login Name )

Original:

echo str_replace('-', ' ', $userInfo-> user_login);
do_action('the_champ_login_widget_hook', $userInfo-> user_login);

My Change:

echo str_replace('-', ' ', $userInfo-> display_name );
do_action('the_champ_login_widget_hook', $userInfo-> display_name );

Those are the only changes I’ve made so far really, other than some other minor things that I was able to do with JS that is all backend, but I’ve only been using this plugin for less than 24 hours and am only using the login feature for one site/platform.

If there’s a proper way to make suggestions to code changes and stuff like that, please let me know, I’d like to make sure I can help out without being annoying, or better yet, I’d rather not just tear the plugin apart and make my own custom version of it.

Best Regards ~
