In the BE we have stored filter operand as IS_EMPTY, IS_NOT_EMPTY, etc. For some reason in the FE we were manipulating IsEmpty, IsNotEmpty, etc. (maybe because they were used before in Views before they were moved to core) So we were converting the operands in the FE from IS to Is (convertViewFilterOperandFromCore) to read and manipulate viewFilters, and then back to BE version to send mutations etc., from Is to IS (convertViewFilterOperandToCore). The migration is now over, so we can remove and simplify that code. (In the 1-5:migrate-views-to-core command we still do the migration from Is format to IS format.)

Does the world need another CRM?
We built Twenty for three reasons:
CRMs are too expensive, and users are trapped. Companies use locked-in customer data to hike prices. It shouldn't be that way.
A fresh start is required to build a better experience. We can learn from past mistakes and craft a cohesive experience inspired by new UX patterns from tools like Notion, Airtable or Linear.
We believe in Open-source and community. Hundreds of developers are already building Twenty together. Once we have plugin capabilities, a whole ecosystem will grow around it.
