Some issues just get ignored or fall down the list depending on the priorities you set for your working week.
Getting the basics fixed and working becomes a necessity when users start to complain about an issue you once believed, “no one will notice or care” about.
Constant tweaking on those smaller less critical (but still annoying) UX / UI bugs will help to reduce the overall queries and will help with retention for those customers not willing to complain but who just jump ship anyway.
So try to make a list of the lesser smaller issues and call it your Tweak List. Then tackle one or more of the tweaks each day.
I actually immediately added a new issue spotted by a customer to the Tweak List and went at it right away. Then solved the issue in less than 1 hour. The customer was amazed and gave high praise and is now a avid promoter of our service.
Nice if you can get it!
