Paizo definitely saw there were some issues with the action economy, since they addressed it requiring 1 action to put your weapon away and another action to draw your new weapon in the remaster when they just made it a single action to swap weapons.
Aside from that there's definitely some stuff I don't require as GM. It's one action to retrieve an item stowed in your backpack, then (usually) a second action to use the item. The rules actually say it's typically another action to Open or Close the backpack or pouch but I feel like 2 actions to drink a potion is plenty and just include the opening or closing into the 1st action to retrieve the item.
