Some work required, still.

Thank you Graham.

I would consider that to be payment enough for the mere copying of work already done by others ... the original commits, which I tracked down:

https://github.com/bitcoin/bitcoin/pull/2861/files (with an informative discussion)

https://github.com/litecoin-project/bitcoinomg/commit/fa960268f1327630aef092463f3ff7dc4b9f66ab (all rounded up into a single commit)

Which proved to be a useful exercise because it revealed a number of later commits extending the feature into the GUI, e.g.

https://github.com/litecoin-project/bitcoinomg/commit/55a1e69851c795c8f25e3999fa901bde0e990d32

Which reduces the task to one of working through the commits, copying the changes and finding the right place in the Slimcoin code to paste them into.

Then I can use the feature. That's the useful thing about FOSS, if you want an extra feature, just add it.

Cheers

Graham
