Hello triplepundit,
Thanks for contacting us and sorry for the frustration!
I’m not sure of the reasoning behind this, although it probably has to be a UX and validation concern.
Unfortunately I can’t find a good place to edit this, without changing the core ‘admin-views/widget-admin-list.php’ file. You could set a new limit there, but that is neither encouraged or recommended. Any change you make there will be overwritten with the next update.
If you use some sort of developer tool, you could also ‘hack’ the <select> <option> value of ’10’ to whatever other number you wanted. I believe if you just edit it the one time it will stick after that. Again though, neither recommended or supported.
Sorry I don’t have a cleaner work around for you. If you have a moment, we’d love for you to submit your idea to our UserVoice forum. We take user ideas and contributions very seriously, and many times their ideas end up in our future releases.
Does this make sense? Let me know if this doesn’t work for you.
Cheers!
