Midfielder Matthew Saunders' 17th-minute strike, his second goal in three games, did the trick for the hosts as they leap-frogged Rochdale to go 12th in the table and just three points away from breaking into the play-off positions.
"It was a hard-fought win, but we knew it was going to be," praised Still.
"I said on Friday at training that I believed this would one of our toughest games of the season - and it was.
"It would have been nice to have moved up a few more places in the table, but if we keep on winning we'll get up there.
"Local derbies are always tough. You have to make sure you do everything you can to win the game, that's the most important thing.
"We had a lot of corners and created pressure, but early season we scored a lot of goals from corners.
"They didn't come off for us, but those sorts of chances ebb and flow.
"We'll keep working on those moves on the training pitch and they'll come right for us.
"But overall I was delighted wit the victory. It would have been great to have got that second goal to make sure of the victory earlier, but we've got the three points."
