"Stub in" is a term commonly used in software development, particularly in the context of programming or coding. When a developer "stubs in" a piece of code or a feature, it means they are adding a temporary or incomplete version of that code or feature, with the intention of finishing or completing it later.

In the context of the sentence provided, "Note: Stubbed this in for now, with the intention to add more data later," it means that the writer has added a temporary placeholder or bookmark for a piece of data or information, with the intention of filling in more details at a later time. The Spanish translation "se agregó esto a modo de marcador temporal, con la intención de agregar más información más adelante" captures this idea of adding a temporary placeholder with the intention of filling in more details later.

It's worth noting that the best translation will depend on the specific context and the preference of the translator or the target audience.
