The “all” button needs to be reworked into something of picture related. At the moment it’s serving no purpose as you can only fit 4 units in there. So either remove it alltogether or replace the upgrades with units.
The main reason why this is so bothersome and clunky is that if a player uses the default F1 button to select all army production buildings, you always have to use TAB one more than than needed to get to the rax/stables/siege workshop etc. tab you want. AT LEAST put the “all” button as the last tab and not the first one.
Yeah my brain keeps stumbling on that stupid all” button… sc2 never had it and i cant get used to it yet
