And on the subject of donors, it's tough to be able to appropriately compensate contributors without some amount of stability of income. OBS accepts donations primarily though Open Collective (https://opencollective.com/obsproject), and while there's a good amount in the bank, it's not being replaced as quickly as the project might need in order to properly fund developers at the level it needs to in the long term. A broader donor base would certainly help bring the stability needed to support that sort of effort.
And you make an excellent point with the lockdown. Now's an awkward time to want to raise funds for the project with so many people struggling financially. In fact, it's probably reasonable to say that OBS's usage has increased so much specifically due to the fact that it doesn't require anyone to pay for it, so it's less likely that the people who use it are able to help fund it.
I will say that there are efforts underway to hopefully address some of the systemic shortcomings that the OBS team has in terms of funding and development bandwidth, but things still move slowly when built on the back of a largely-volunteer workforce.
Is there anything really obvious in the GUI that I missed? A small reminder, even after using it a few times, might help unobservant folks who want to support free software, like myself.
I've certainly told many people about OBS and will continue to spread the word but short of donating I'm not sure how else I can help out (and I'm short on cash thanks to the lockdown).
