It can be absurdly hard to select and edit a line/polyline in draw, if the line/polyline is entirely in front of another object. In my experience, nine time out of ten, LibreOffice Draw interprets my attempts to select the line/polyline as an attempt to drag and drop the object behind it. So select-oops-undo, select-oops-undo, select-oops-undo... I am clumsy, but even so, it seems like a bit too much.
I've tried with image and line and have not problems to select line. Please attach test file.
I tried with rectangle and line and it didn't seem problematic. Win 7 Pro 64-bit Version: 5.1.0.0.alpha1+ Build ID: b216cc1b8096eb60c27f67e8c27b7cd756c75e38 TinderBox: Win-x86@62-merge-TDF, Branch:MASTER, Time: 2015-11-12_00:06:20 Locale: fi-FI (fi_FI)
I had an agonizing time for hours yesterday, but it seems to have cleared up today. I can select lines and other small objects about 80% of the time instead of 10%. I was using the laptop monitor yesterday, and an external monitor today. I was using an external mouse both times.
Ok, let's set to WFM, then. You can also select shapes using the navigator, but there is a bug that forces you to name the shapes first: bug 62851 Name a shape: select it, Top menu Modify - Name. Then in the navigator you can double-click them to select. This is surely a handy feature, if having a lot going on in certain parts of your drawing. In such a busy scenario, I think it would be just as chaotic to select stuff with mouse-clicks, even if the hit area of lines would be increased.
Not practical. It would require a lot of extra mousing and typing, switching between mouse and keyboard, and would impose a lot of extra arm strain. Definitely not practical for users with rsi.
