2024-11-14 Climate Emergency high cpu load and ram usage for no reason
2024-11-09 eelkenet It does what it needs to do, true. That's why I won't rate it it with a single star. But it is causing an insane CPU use on my Mac, draining my battery within an hour. Took a lot of work to find out the cause. Please fix this ASAP!
