This plugin allows an admin to create simple table reports from the usermeta database table.
Maybe, depends on the time I have available. I already have a full-time job.
The code is not optimised for performance. To illustrate, when generating the report, the plugin first selects all the users in in your WordPress intallation. For each user, it makes a separate query for each meta-key you have choosen for the report to find the value. This could potentially generate lots of queries towards the database.
Example: you have 1200 users in your database, and want to produce a report using 7 report fields:
1 query to find all users: 1 query 7 queries for each user: 1200 x 7 = 8400 queries In total: 8401 queries
I have tested it with about 200 users and genereated reports with 10+ fields. It still takes less than 5 seconds on my test equipment. The usermeta queries are all small and hits the default indexes.
