Is your feature request related to a problem? Please describe.
I have SMLM data which has upwards of 10 million localisations, and when loading it in it crashes.

Describe the solution you'd like
There may already be a proposed solution/previously raised issue which addresses this but I couldn't find it. The solution would just be simply the ability to visualise such a number of points, but I understand that this may be beyond the remit/require major changes which cannot be implemented.

Describe alternatives you've considered

Additional context

Are you prepared to work on it?
If there was a proposed solution I would be happy to help.
