I've been using Dia, and this got better after the recent inclusion of Spaces similar to Arc.
But, I'm suffering from RAM issues. Got 24GM RAM M5 (Non-Pro) MacBook Pro and about 10-15 tabs open, I'm consuming 19GB RAM with 5-9GB RAM in swap.
I mean... now I'm wondering if I should've got higher RAM.
Since I came from Air M1 8GB RAM, I thought 24GB is plenty enough but seems like not.
