Just like in Writer, one often wants to indent / increase the level of _paragraphs_ in Impress. We get this sort of for free when bullets are enabled: A tab press increases takes us to the next level, typically increasing the indent. This is what Increase/Decrease Indent should do, regardless of bullets, when nothing is selected. Instead - it affects the entire textbox, which is less useful and also, I would argue, not what users would expect.
Created attachment 184189 [details] document to test I agree that we should be able to indent a single paragraph in a text box. Reproduced in: Version: 7.6.0.0.alpha0+ (X86_64) / LibreOffice Community Build ID: 28ff4647e9dac8eebe3a169e828bacc8dc78e363 CPU threads: 8; OS: Linux 5.15; UI render: default; VCL: gtk3 Locale: en-AU (en_AU.UTF-8); UI: en-US Calc: threaded And: Version: 6.3.6.2 Build ID: 2196df99b074d8a661f4036fca8fa0cbfa33a497 CPU threads: 8; OS: Linux 5.15; UI render: default; VCL: gtk3; Locale: en-AU (en_AU.UTF-8); UI-Language: en-US Calc: threaded
In my opinion, for changing the spacing between border and text for the whole text, it makes more sense to use the text box's Text Attributes. Interestingly, in Writer, the indent buttons are greyed out when editing text inside a text box.
Format > Paragraph does allow changing the indent for single paragraphs. It's surprising the sidebar (and now toolbar) buttons don't do the same.
