I have multiple timeframes of same instrument on screen. Hence price labels on price axis of each chart are not necessary. The ability to turn price labels on and off under the “Chart settings” menu for each chart would enable me to save some precious horizontal screen space.
For those of us traders who use multiple time frames on the same instrument, freeing up more space is beneficial. I posted a request to implement a “'Workspace Only view” where the tools on all sides are hidden by pressing Shift-F. That would free up a lot of space and one could still trade because all the trading tools are in the modules (the workspace) – charts or DOMs. At any moment, if one needs to see any of the toolbars, they just press Esc, and they are back instantly. Maybe you could take a look at my post. I think that feature might also be beneficial to traders like us.
I gave your “toggle price labels” feature a vote up.
