Mailspring allows setting a custom signature for our emails. This is great. However, in many occasions we want to modify such signature, just slightly. For instace, you may want to change “Best regards,” for “Kind regards,”. This is AFAIK not possible, unless one removes the signature altogether.
I guess the solution is straightforward: pasting the custom signatures in each email as text rather than a sort of immutable image. I don’t know how feasible this is, but standard clients (gmail, outlook, etc) allow doing so, so why don’t we?
