Redmine

Displaying a Gantt chart by default not from the current month but from the previous month.

We are a company trying to adapt redmine for our purposes.
And we have some small suggestions for improvements.
We are ready to pay for these improvements. How does it do better?

For example, we need a patch for this feature.

ps: (in Russia)
Мы из России было бы удобнее работать с русскоязычным разработчиком.
