Is "Yucata Hotkeys" on Chrome Web Store Safe to Install?

[email protected] · chrome · v1.0.7

This extension will add hotkeys to yucata.de games to enable a hotkey for "finish turn" and other actions. A tooltip is added to the bottom right of the game screen - the hotkeys added are currently mainly for Machi Koro, but some of them will work with other games i.e. press 'f' for finish turn, press 'n' for next game. Machi koro styles will also be affected. == Latest Updates == - Hotkeys now work regardless of language set on keyboard (e.g. 'φ' will trigger 'f') - Hotkeys no longer trigger while typing in the chat
