I would like to see the grid manager added to the meta7 client with a the "Map TP between girds" Like in meerkat i think that was a wonderful feature in meerkat that i personally used/use quite a bit to tp from one grid to another. In Meta7's case it would make jumping to sl to tfer L$ to M$ a lot easier and more streamlined in my opinion and also of backing up personal builds to transplant from one place to another.

You are able to enable a grid-manager similar list already with the currently available meta7 viewer by pressing CTRL SHIFT G on the Login Screen.
"Agni" is the SL Maingrid.
It will stay enabled automatically for each viewer start unless you press CTRL SHIFT G again.

The actual teleporting from meta7 to another opensim grid or to the SL Grid is currently not available.

I hope this was helpful to you!

Meerkat did a LOT of changes to the viewer to make that possible. The LL viewer code does not make that easy, as it in general assumes that there is only one login session per run of the viewer, and that ending the login session stops the viewer from running. The meerkat "TP to other grid" is really just a logout of one grid and login to the next.

We don't base the meta7 viewer on meerkat, but on emerald, so would have to replicate all that work. A big load of work, there are more pressing things to work on, and there are not many of us doing the work. On top of that, most of the third party viewer coding is still being done on a voluntary basis, we have day jobs to consider. It is on my personal TODO, though very far down. First I want to beat the horrid LL code into shape with a large baseball bat, so that future work like that will be easier. lol

As an alternative, even my ancient computer can login twice running the viewer twice. If all you want to do is pop into SL to deposit funds in a meta7 ATM, then the major performance degradation you get on ancient computers like mine is not so much of a problem. Modern computers will have no problem. You might even be able to do that with one of the text based viewers like meta bolt (no relation to meta7), I never tried it.
