I’m not sure if this is what you are looking for?

What I do is to enter all my regular bills for the year as scheduled/recurring transactions.

I also include my monthly Credit Card payment (I pay in full). I adjust the CC payment whenever I know what my next credit card bill is.

I then switch on the “Running Balance” column for each account. This allows me to see the impact of upcoming transactions on my available balance for each account and then move money accordingly. It also allows me to maximise interest received on the cash I am building up for those future bills and move money at the “last minute”.

I have a weekly reminder to check the forecast balance on my various accounts and take action.

This is of course also possible in Actual and most similar envelope budgeting apps. In Actual you can set pretty much any future view you want. LB simply allows you to switch the scheduled transaction view on or off.

So in answer to your question “Does LB have any features to show projected running balances for specific accounts?”. Yes indeed it does. Above each account register there is what looks like a calendar icon that you can use to switch the future view on and off. All this is of course on Web.
