Hoseo University LMS Plus
A browser extension that shows Hoseo University LMS attendance at a glance
A browser extension I built because the university LMS attendance page was just too inconvenient. It organizes attendance status per course so you can check everything in one place.
Why I built it
Every time I logged into the LMS, I had to check attendance for each course one by one.
As the number of courses grew, it became harder to grasp the overall attendance status at a glance, and the process of checking each course individually felt increasingly tedious.
So I thought,
“It would be nice to see the full attendance status on a single page.”
and ended up building a simple browser extension.
How I built it
The overall flow is fairly straightforward.
- Parse the DOM of the LMS attendance page to extract per-course attendance data.
- Transform the extracted data into the format I need.
- Display the attendance status per course in the extension’s popup UI in a readable way.
Key features
- Check attendance status per course
- See the overall attendance status at a glance
- Automatically extract attendance data from the LMS page
- Use it easily as a browser extension
Release
Rather than keeping it for myself, I published it to the Chrome Web Store so others could use it too.
It started from a small inconvenience, but it was a project where I got to experience the full arc: idea → implementation → actual use → release.
Finding something inconvenient in a service I use regularly and solving it myself was a surprisingly fun process.
