Well done, that's progress. It's an odd thing but if you said on any modern car forum that you'd finally managed to get a door open you'd be met with "huh ?" and yet with an old Lotus it's considered a milestone !
Joking aside, I'll just repeat what the others have said and don't get taken in by a smooth action or no vertical play in the door. The snag is that the hinge pin is mild steel and it locates into aluminium (?) bushes cast into the upper and lower body panels. What can happen is that the steel pin rusts solid into the threaded steel inserts in the door itself and so the opening movement takes place between the pin and the aluminium body bush rather than the pin and the door insert sleeve/bush/whatever it's called.
This is bad news because you think everything is ok but you wear away the aluminium inserts and then the door exhibits vertical play. You can adjust a small amount but it will rattle over bumpy roads and inevitably you need to replace the bushes in the lower sill and upper wing. That is very difficult but if the wear isn't so bad then you can drill out and fit a brass insert sleeve to restore the fit.
It's better to avoid that sort of thing, so while it's all apart get your torch and open the door. If the pin itself moves as you open then stock up on plasters and change for the workshop swear box because there's more joy to come

ps - if you don't go for Bank's hinges then at least replace the pin with stainless rod, it's 1/2" IIRC and off the shelf at metal stockists.
