Greetings! Welcome to the second blog of the series “1st-stage GUI setup”: September 2023: Partly Wine-syncing setupapi October-November 2023: Making partitioning UI work December 2023: First tests As you may have noticed, I have been quite silent about my work and not regularly writing blog posts about what I have done so far. Well, I am more concerned about getting actual code written and working before discussing about it, instead of doing that about half-done not-yet-tested code; much like what the GUI setup was during these previous months.
