Default client's map feature

[Procne]

I'm looking for a custom client which improves default client's map feature.

In particular I'm looking for client which can:
1. dump tiles from default map to files which can be used for merging
2. adds zoom in and zoom out to default map
3. import / export default map data from / to default client

Is there any client like that?

Not yet, all public custom clients still use their own map functions and havent hooked into the default map for data yet
