问题
RubyMine 6.3.3 (which uses the IntelliJ codebase) seems to quietly close file buffers when I have ten files open and open another. How can I disable or change this limit?
回答1:
Go to Preferences -> Editor -> Editor Tabs. Under "Tab Closing Policy", set "Tab limit" to whatever you like. Use the maximum of 99 if you don't want tabs to auto-close at all.
