Dear RKWard Devs, Since I was recently working again more with RKWard (analysing usability data…), here are some usability problems I found. I tired to estimate how hard they are to fix, so one could focus on the most effective fixes.
I split them in different mails, so that the issues stay separated. 1) Reading CSV Data =========== First row as col names (easy/medium difficulty fix) -------------------------------------------------------------- It took me a long time until I found how to get the first row as column name. Assumed reason: The checkbox for the option (nicely put on the first tab!) is somewhat squeezed between other elements. On Linux it looks like it is part of "quick options", on Mac this impression is even more extreme, since it resides in some darker-colored box. Violated Heuristics: Usability, Standards (all other options have some sort of headline) Proposed Fix: Give it a space on its own (an own line) and/or a headline Aside there are several smaller issues I found. Wordings (Easy fix) -------------------------- a) In "Column names in first row" (1st tab) it is unclear if the first row is the CSV’s or the resulting data.frame. (Suggestion: "Use first line as column names" (?)) b) "Default": On the second tab there are many "Defaults", but it is unclear what this default is. c) "Edit Object" (1st tab, save to options): This seems to open the object after import in the table view, but it suggests it somehow directly changes some object (like a mixin or an overwrite...) (Suggestion: "Open after Import" or "View after import") Active/Inactive Fields (Medium) ----------------------------------------- Depended on other fields, some radiobutton options are active or inactive. Sometimes it is hard to follow why, and the many inactive options irritate Possible fix: Using Dropdowns (?) like in RStudio’s import Preview (Difficult) ----------------------- This is probably hard to implement but a preview of the first 5 or so imported lines would be great (also RStudio inspired) Flow: Call the file selector (easy to medium) ---------------------------------------------------------- Before any option makes any sense, I file needs to be loaded. So flow-wise it would make sense to open the file picker right away. It also would match user expectations, since it is standard in many other applications.
