The Problem
I have several large email accounts for work, so there are times it takes a while for Mailspring to scan through the inbox for changes and so the bright notice shows a lot.
Proposed Solution
Have an option for it to just be an alert icon at the bottom to be less intrusive for those that have huge inboxes and get this a lot.
Alternative Solutions
Have a setting to increase the threshold of what causes it to pop up.
Context
I spend most of the day with this box on my email app. It gets to be annoying to a point it serves little purpose to alert me that there is an actual issue.
