I started working on TabSorter2 in 2017 because I was frustrated with my chaotic tab life. I had up to 300 tabs open daily. I couldn't find anything that would help me with this problem, so I decided to write my own extension for personal use. 6 months later, I had about 500 users along with requests for features and bug fixes. People were appreciative of this tool, so that motivated me to keep working on it. 5 years later, I had about 2,000 users by pure organic searches, still an influx of custom feature requests, and only $15 on the app donation page. I love working on this app, but what started as a fun side project has become too time-consuming with little reward to myself for the continuous work put into it.
4 months ago, this app was taken down from the Chrome store for permission issues. People wanted it back, so I spent the next few months rewriting close to 75% of the app while adding new features amidst working my full-time job. I am almost done rewriting it and would like to release it to the public. In order to keep maintaining and improving it, I am thinking of charging a small monthly fee of $3.99. Knowing that people value my work enough to pay for it would motivate me to keep maintaining this app and to create more Chrome extensions geared to productivity. I am curious to know if this is reasonable and if people would be willing to pay that amount.
