Micro-scripts help so much, and you can reuse them. I lead with a cheerful timebox like 'I've got one minute while this compiles, then I'm heads down.' Then I pair it with a physical cue, like a half-step backward or a swivel toward the screen. My ridiculous time tracker actually improved this because I say 'dropping back into focus block' and people respect it. It feels dorky, but consistency makes it friendly instead of abrupt.
Think about total cost over time. Two cheap kits can trap you into two sets of batteries and chargers that both need replacements later, which is how it gets expensive. A bare tool that uses the packs you already have keeps everything simple and you carry one charger in the bag.
If the packs you own are not the same platform as the drill you are eyeing, assume they will not fit. that model on the sticker does not mean universal.
